00474: planet2 bmp mapping adds light past the terminator

« 00473 | Issues | 00475 »

Summary: planet2 bmp mapping adds light past the terminator

Created: 2013–02–01 11:22

Status: Released

Category: Request

From: frankie

Version: 2.2

Released_In: 2.3

Description:

When using a bump map layer on a planet, the normal of the surface is what determines the lighting. Given some of the steep walls of craters on the moon, this can cause some lighted spots on areas past the terminator that should be dark due to self-shadowing.

This is a request to change the lighting calculation so that the spheroid normal of the planet is first used to figure out which side of the terminator you are on, and then apply the bump mapping calculation.
