Bug 51771 – ILUT OpenGL textures upside-down in devil-1.6.6

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Dirk Gerrits 2004-05-22 17:07:58 UTC]

When using ilutGLBindTexImage or ilutGLLoadImage, devil-1.6.6-r1 loads the textures into OpenGL upside down. This does not occur with 1.6.1. Note that it is the ILUT transfer to OpenGL that goes wrong, loading the file with ilLoadImage produces the right result with both versions.

Reproducible: Always
Steps to Reproduce:
1. Make sure you have devil-1.6.6-r1.
2. Make a program that uses ilutGLLoadImage and draws a textured quad.
3. Compile the program and run it.
Actual Results:  
The texture was upside down with devil-1.6.6-r1, even though the texture and
vertex coordinates were correct. (OpenGL has a right-handed coordinate system
and texture coordinates run from lower left to upper right.)

Expected Results:  
The texture should be oriented correctly, as with devil-1.6.1.

The correct behaviour that I get with devil-1.6.1 under Gentoo I also get with
devil-1.6.5 under Debian and Windows.

Not my area.

i just added devil-1.6.7 to portage, try that out please :)

btw, there is no 1.6.6-r1 ... i assume you mean 1.6.6-r2 ...
