Release notes version 0.1.8

Environment lighting python API

The user can now access to environment lighting attributes for custom shader purpose, these values are read only and named:

KX_WorldInfo.envLightEnabled
KX_WorldInfo.envLightColor

Shadow slope bias

Shadow slope bias is a technique to avoid shadow acne based on the receiver geometry slope, to proceed this bias the fragment position to test for shadow is moved of the view normal multiplied by a factor exposed in UI:

Left: bias of 0.1 and slope bias of 0.5, right: bias of 3.0 and slope bias of 0.0, notice the shadow gap.

Blenderplayer anisotropic command option

Anisotropic filtering is technique to improve the texture mipmapping, it had four values possible: 2, 4, 8, 16. These value can be set in blender in user settings and now too in the blenderplayer by specifying the option -m in command line:

blenderplayer -m 8 file.blend

Clean up and refactors

• Use one display array bucket per deformer. (see 1b30104)
• Render with storage info instead of display array bucket. (see 6845f2b)
• Use VBO index buffer for polygon sort. (see 8e2a271)
• Simplify derived mesh draw. (see 034494)
• Remove unused function and arguments in GameLogic/. (see e7ef47b)
• Refactor render node system. (see 0aad135)
• Optimize timer logger. (see 3e25f79)
• Use KX_GameObject in KX_Scene and object actuators. (see 7a91011)
• Manage python namespace in SCA_PythonController. (see cfcf5fa)
