Simple solar system using textures from NASA.
python manage.py runeffect examples.system
Basic example of using transform feedback. Thousands of particles are being affected by newton's law with a pulsing gravity field in the middle of the scene. Particles are drawn as points were a geometry shader emits billboarded quads.
python manage.py runeffect examples.feedback
Geometry shader example. We're drawing points were the geometry shader emits a cube on each point and slightly modifying the position of each cube. The texture on these cube is an fbo texture of a spinning cube just for fun.

Example loading and drawing GLTF 2.0 scenes. The Atrium Sponza Palace, Dubrovnik, is an elegant and improved model created by Frank Meinl. The original Sponza model was created by Marko Dabrovic in early 2002. See README.md for more info.
python manage.py runeffect examples.sponza
Example loading a text file displaying it on the screen. The text is drawn using instanced rendering were each instance is a character in the file. This may not be the most efficient way for drivers emulating instancing. Text renderer (render to texture) is an alternative.
python manage.py runeffect examples.textwriter
Example loading a text file displaying it on the screen. The text is rendered to a texture at initialization. We simply display the texture each frame. We are limiting the texture height to 8k in this example.
python manage.py runeffect examples.textrenderer
An example of what can be achieved with a relatively simple shader and a fullscreen quad. Originally created by Erik "Dran" Norby for the demo "Sonic Room".

Ray marching example by Arttu "helgrima" Tamminen.
python manage.py runeffect examples.raymaching
Simple tessellation example using a height map. The original vertex buffer is a 8 x 8 resolution grid with 128 triangles. Each triangle is tessellated using inner and outer level of 64 giving us around 780.000 triangles. We toggle the draw mode between textured and wireframe over time. Because the tessellation evaluation shader reads from the height map we get curved tessellation instead of all triangles ending up in the same plane.
