Image Modified

After baking is done, the next step is to run ‘txmake’ on each image to create a MIP-mapped cache-friendly texture in .tex format. These textures can then be read during rendering using e.g. OSL’s texture() function. Figure 2(right) shows the Cornell box and diffuse sphere shaded using the precomputed illumination textures (while the reflection in the specular sphere is rendered with ray tracing).
