I am trying to display a 50000 x 6000 image. I have tiled the image into 2048x2048 jpg tiles. With texture compression set to COMPRESSION_ARB they load correctly. With this removed I get blank textures. See attached image.
I have tried PCs with more graphics memory and RAM with the same result.
Here is the tiling code:
Code:
for v in range(0, vTiles):
for h in range(0, hTiles):
quad = viz.add(viz.TEXQUAD)
quad.translate(h-hTiles/2.0, -(v-vTiles/2.0), 4.0)
counter += 1
fileName = 'crop_' + '%02d' % counter + '.jpg'
texture = viz.add(fileName)
# texture.compression(viz.COMPRESSION_ARB)
texture.wrap(viz.WRAP_S,viz.CLAMP_TO_EDGE)
texture.wrap(viz.WRAP_T,viz.CLAMP_TO_EDGE)
quad.texture(texture)
