Lux Tutorial

To get started with Lux, go through the tutorial before anything else.

Looping Demos

Specific Lux Features

• Basic texturing.
• Subimages: changing only bits of a texture at a time.
• Simple conditionals: branching support.
• Discarding fragments to poke holes on primitives.
• Loop-Blinn font rendering lets us quickly draw resolution-independent, pixel-accurate text with very few polygons.
• Texture-based font rendering: in case high-performance is absolutely required, the standard technique of drawing text from glyph textures is also available.
• Picking: how to have Lux tell you on what you clicked.
• Depth Readback: reading the depth of a pixel in Lux.
• Rendering to a texture lets you use the result of drawing operations as input to others.

Miscellaneous

• The Utah Teapot.
• Showing off how to specify per-vertex computations.
