I don't think any of the hardware drivers uses it.
Adreno has different texture instructions depending on the desired return type. If you use a float return type on an int texture, you will get a floating point value of that integer (i.e. if the actual textured value were 100, you'd get 100.0f returned if you did sam.f32). -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
