Terms and conditions:

• You have explicit permission to use gameapi builder and for creating 3d model, the node graph, and deploy the end result to a web site of your choice. From builder tool you also have our permission to take screengrabs and videos using external screen grabbing software.
• You are not allowed to add copyright infringing content to any url slots inside builder tool. While builder can filter out some of that usage, the checks are not perfect and if that happens, we basically cannot do anything to protect our end users from the content owner's legal actions
• For children at ages 10-18 years old, gameapi builder provides safe learning environment where it is difficult to do large mistakes like publishing sexual material, copyright infringements or racist brainwashing.
• GameApi builder and web site does not create additional communication channels for human communication. This is to ensure that our end users do not suffer communication overload
• is not a social media platform. Correct designation is "Content Creation Tool Provider" and "Web Publishing Enabler" and also "Content Publisher"
• Standard disclaimers apply, no warranty or ability to return purchased material
• How we handle licensing is that we try to use the licenses that each community is natively using. So open source folks gets open source license, and commercial people get commercial licenses. Different directions (from our point of view) get different licensing. You can consider it "Eat your own dogfood" style license. If commercial people want to move to use open source license, they need to find from open source community where our software is available via open source licensing. That find operation is necessary. When our own web sites distribute the software, license is dependent on who is asking for a license. It is important to note that there can be different kind of users in the marketplace and we try to cover all use scenarios. Asking us for a license is easiest way to get a license that is suitable for that purpose and use case. This is why there is no licenses available in the web page, but we try to handle all license requests manually as quickly as possible. Software upgrades are following the same licensing that was originally agreed, so there will be people downloading the software via different licensing terms.

frequently asked questions

What is meshpage.org?

• meshpage.org is groundbreaking way to bring web to next level. Next generation web will be 3d with meshpage.org's technology.

How does the site work?

• DOWNLOAD: You download the builder tool
• CREATE: Create your powerful message with 3d technology
• CODEGEN: You get piece of c++-like code representing animation
• PUBLISH: place 3d engine to your web server
• ENJOY: Then open the animation in your browser

What are the advantages in your approach?

• OpenGL based software-only solution, so no need to buy a camera
• File size is very small. The file size is like 30 lines of c++ code, instead of megabytes of video files
• It's based on "designing the future", instead of "recording the past"
• Displaying models works via URL's: normal web technologies are used to transfer animations to other computers on the planet

What are the disadvantages?

• Work amounts are higher than simply pressing "record" button in a camera.
• Designing 3d animations usually requires some planning
• The tool is slightly more complicated than we wanted
• Flexibility of the underlying software is always a problem
• End product sizes are pretty small, so you can't expect full length movie as the output of this process
• Different animation models are very limited -- basically just translate/rotate
• We don't have sound or music support at all, because it's fundamentally based on recording industry technology, and we're not experts in that area.

Is there a 3d model viewer that uses your engine?

Yes. It's here Useful other sites which you can drag and drop content to the viewer are at least:

• sketchfab
• Thingiverse

If I just want to deploy simple gltf file?

Check our gltf-to-zip converter at Here.

Now, if I got index.html, how do I embed it to my article

<embed src="index.html" width="830" height="630">

What is the minimal node graph that can be deployed to web?

Important part for deployment is the properties of html_run, since it contains url to your hosting space, which you need to change. This ensures that any urls that you load inside the node graph can be fetched from your hosting space. Unrestricted url access is not allowed for copyright reasons.

Web server config(.htaccess) should be something like the following: (you should change the url)

Header set Access-Control-Allow-Origin "https://meshpage.org" 
Header set Cross-Origin-Embedder-Policy "require-corp" 
Header set Cross-Origin-Resource-Policy "same-site" 
Header set Cross-Origin-Opener-Policy "same-origin" 
Header set Access-Control-Allow-Headers "range"

How to setup http cache with the engine?

We recommend in .htaccess:

Header set Cache-Control "max-age=604800, immutable"

(this avoids small problem with browsers deciding different caching strategy for .wasm and .js files and serving mismatched files for the users, causing EM_ASM crashes)

What about compressing the huge engine files?

For nice performance speedup for network, you should enable brotli compression in the web server too:
.HTACCESS Changes:

AddOutputFilterByType BROTLI_COMPRESS text/xml
AddOutputFilterByType BROTLI_COMPRESS text/css
AddOutputFilterByType BROTLI_COMPRESS application/xml
AddOutputFilterByType BROTLI_COMPRESS application/xhtml+xml
AddOutputFilterByType BROTLI_COMPRESS application/rss+xml
AddOutputFilterByType BROTLI_COMPRESS application/javascript
AddOutputFilterByType BROTLI_COMPRESS application/x-javascript
AddOutputFilterByType BROTLI_COMPRESS application/wasm
AddOutputFilterByType BROTLI_COMPRESS application/x-font-opentype
AddOutputFilterByType BROTLI_COMPRESS text/plain
<files *.wasm>
SetOutputFilter BROTLI_COMPRESS
</files>
<files *.ds.*>
SetOutputFilter BROTLI_COMPRESS
</files>
<files *.ds>
SetOutputFilter BROTLI_COMPRESS
</files>
<files *.data>
SetOutputFilter BROTLI_COMPRESS
</files>
AddType application/wasm wasm
AddType application/x-gameapi-binary ds
AddType text/plain mtl
AddType application/x-font-opentype otf

Then /etc/apache2/sites-enabled/000-default.conf probably should have:

       <IfModule mod_brotli.c>
        AddOutputFilterByType BROTLI_COMPRESS text/html text/plain text/xml text/css text/javascript application/javascipt application/wasm application/x-javascript
	</IfModule>
	<IfModule mod_headers.c>
	RewriteCond "%{HTTPS:Accept-encoding}" "br"
	RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
	RewriteRule "^(.*)\.(wasm)" "$1\.$2\.br" [QSA]
	RewriteRule "^(.*)\.(ds)\.(..)" "$1\.$2\.$3\.br" [QSA]

	RewriteRule "\.wasm\.br$" "-" [T=application/wasm,E=no-brotli:1]
	<FilesMatch "(\.wasm\.br)$">
	  Header append Content-Encoding br
	  Header append Vary Accept-Encoding
	</FilesMatch>
	<FilesMatch "(\.ds\...\.br)$">
	  Header append Content-Encoding br
	  Header append Vary Accept-Encoding
	</FilesMatch>
	</IfModule>

Then you need brotli packages:

  sudo apt install brotli -y
  sudo a2enmod brotli
  sudo systemctl restart apache2


What technologies are you using to provide the features of the site?

C++
php
OpenGL
SDL2
glew
emscripten
libfreetype
stb_image
openvr
holoplay
tiny_gltf
(normal browser environment)

In addition to these external stuff, we have internal development in the following modules:

GameApi
GameApi Builder/editor
web_page
mesh-page
iot_main
parser2

What kind of features are available in the base system?

OpenGL instancing
3d mesh data structure
triangles/quads/lines/cones/spheres/cubes/torus
colours/normals/texture coordinates
materials like snow/brashmeta/web/distance fields
shading
animations/movement/matrices
skeletal animations
vertex animations
recursive shapes/trees
waveforms
volumes
2d and 3d rendering
sprites / bitmaps
circles/rectangles/triangles in 2d
fonts/text rendering
etc..

Why do tool menus not do anything?

you can link boxes whenever the labels match
display menu from right mouse button is disabled until linking has been completely done from the left side of the boxes -- this is because left side is inputs, and right side is outputs, and all inputs need to be available for box to work correctly

What keybindings are there in the tool?

ctrl-s saves the data to mod.txt
'a' rotates the model in most dialogs under "display"
'd' rotates the model in most dialogs under "display"
delete (in box title bar) deletes the box
esc exits the application
esc (in blk_window) exits the full screen mode

Trackpads, touchpads and drawing tablets do not work with the technology?
This is known problem, but we don't have solution to the problem. The emscripten_set_wheel_callback() function sends events
 that are not suitable for getting the trackpad to work properly. In ubuntu, we've found that changing settings in gnome and
 disabling "two finger scroll" and enabling "edge scroll" can help it a little, but our current recommendation is to disable
 the trackpad's completely from gnome settings.

The main problem is visible in zoom feature, when mouse wheel is being mapped to the zooming of the 3d models. The trackpad's
 are not able to simulate mouse wheel accurately/consistently enough and we were unable to figure out why gnome's "two finger scroll"
 sends always positive deltaY, when both negative and positive values should be available in the callback.

We haven't checked what needs to be done to get trackpads working in windows.

Why isn't sounds/music working?

Current status of sound/music routines is that pthreads and sounds are
not working at the same time.
Thus to get sound working, you need
to disable pthreads, and get slower prepare time in 3d model loading
phase. This can be done by not enabling crossOriginIsolation,
 then the
scripts will automatically fall back to non-threaded version of the
code.

What tools you should try immediately?

m_snow, m_flat for shading
anim_translate/anim_rotate for movement
move_ml for movement
seq_ml for moving from one scene to another
cube/sphere/cone/torus for basic shapes
p_render/m_bind for basic rendering
p_render_inst/m_bind_inst for OpenGL instancing
li_from_polygon/li_to_cone/random_quad for some amazing effects
static_instancing/ms_static_inst for cpu side instancing
blk_window and MainLoopApi features to finish your product

I get browser crashes when loading your web site in windows machines
Here's steps to fix some webgl2 problems in windows:

about:flags -> angle graphics backend -> opengl

It seems the default d3d11 webgl2 backend is somewhat broken, but happily
its possible to fix the problem by using the opengl backend.

I get error while loading the animations

With new pthreads support in the site, browser settings need to be changed
Chrome users: chrome://flags should have webassembly pthreads enabled
Firefox users: about:config shuold have shared.memory=true

What browser should I use?
On my laptop I get the following benchmarks(this test: here(

some users have reported 700fps, but with high-end video card
Brave browser gives about 147fps
firefox is 54fps
Chrome is at 30fps
