I’ve been reading the docs for a while now, but so far I haven’t found what I’m looking for.
I want to be able to procedurally generate a bitmap to use as a texture, and later as a basis for a terrain mesh. Something tells me that the Asset class, and particularly the data property of that class, is where I need to look. However, I’m not sure what that JSON blob needs to look like for a texture asset.
Anyone have any pointers?
You can create a texture this way, and then assign it to the material:
createTexture(device, format, size) {
return = new Texture(device, {
width: size,
height: size,
format: format,
addressU: ADDRESS_CLAMP_TO_EDGE,
addressV: ADDRESS_CLAMP_TO_EDGE,
type: TEXTURETYPE_DEFAULT,
magFilter: FILTER_LINEAR,
minFilter: FILTER_NEAREST,
anisotropy: 1
});
}
const texture = createTexture(device, PIXELFORMAT_R8_G8_B8_A8, 2);
const pixels = texture.lock();
pixels.fill(0); // fill it up with black pixels, but you can use numbers in 0..255 range
texture.unlock();
