Well, this does not explain this strange anomoly:
after changing the pixels, i set the texture of the appearance with the texture of
whose pixels i have retrieved; this does NOT change the appearance texture though (as
I have noticed and as you pointed out); however, if i clone the texture (after i have
modified the pixels) and set the clone as the texture of the appearance, the textures
do get updated; this seems contradictory to what is supposed to be happening.
Here is what I am doing:
// get the pixels
pixels =
((DataBufferInt)((ImageComponent2D)textureArrayCurrent.getImage(0)).getImage().getRaster().getDataBuffer()).getBankData();
// modify the pixels
// blah code here
// clone the texture whose pixels i retrieved above
Texture2D texCopy = (Texture2D) textureArrayCurrent.cloneNodeComponent(true);
// set the texture of the appearance
appearance.setTexture(texCopy); // weirdly, this changes the texture
thanks for the previous quick reply but i am still a little confused,
