While working with the same coarse dataset I mentioned a moment ago, I noticed what I think might be a coordinate miscalculation when placing the draped image texture onto the terrain. Some testing suggested there might be a half-pixel misalignment of the source imagery. I'm trying to reconstruct a test case that I can share that demonstrates this. I notice there are some ifdefs in the VPB code for this, but it's unclear to me if they're correct. This would be a half-pixel in source image space, not in OpenGL texel space, so in my case of 30m Landsat imagery, it would be off by 15m. It could go un-noticed when using imagery sources of higher-resolution, as the offset would therefore be smaller.
Anyone noticed anything of this sort? -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
