Light and Shadows example

v0.8.2

Depth bias is no longer hardcoded in the shader and can now be customized by setting light_and_shadows.depth_bias or in the sun object. What’s this? To reduce the Peter Panning effect (shadows detaching from objects) in shadow mapping, you need to adjust the shadow bias, a value that offsets the shadow depth. Too high a bias causes Peter Panning, while too low a bias leads to shadow acne.

A new Tinyworld example has been added. It uses tilemap, pixelart textures, billboard sprites and different material variants.

What is the FPS on your device?

60 FPS with Intel Iris Xe integrated graphics. I assume it could go higher if vsync were disabled.

A steady 60 FPS with 4GB RAM and integrated Intel HD Graphics 4600 on a corei5 running Linux. Very nice work! Once I got to around 700 objects, it stuttered briefly to 59 FPS, but then reverted back to 60.
