We're using large high-quality textures (480x320), but the image mapped onto
the cube is quite chunky even when we are using the Apple QuickDraw 3D
Acceleration card, and the animation seems to be slower and jerkier. What's
TextureEyes' secret?
A No secrets! TextureEyes is a straightforward implementation of the texturing
of QD3D geometries.
The problem is that your texture is actually of too high quality. QuickDraw 3D uses a tri-linear MIP map algorithm to obtain the best possible quality texture mapping.
To create a MIP map from an image requires creating sub-images sized for every
inverse power of two; i.e. 1/4, 1/16, 1/32 etc. The process of creating a MIP
map for every texture takes time, and larger textures will require longer.
TextureEyes uses a 128X128 source for its movie and video textures.
