povray

问题 I am using the following POV-Ray loop to plot sRGB coordinates in other color spaces. The loop only generates points along the outer surface, and then connects them with triangles. Since the sRGB space is a sort of twisted cube, that means 6 outer faces and 8 vertices. #macro cie_calc_gamut_xyz_srgb() #for (i, 0, cie_sample_count_srgb) #for (j, 0, cie_sample_count_srgb) // side 0 & 3 #local cooRGB = <i/cie_sample_count_srgb,j/cie_sample_count_srgb,0>; #local cooXYZ = cie_convRGB2XYZ(cooRGB);

问题 I know this has been asked before, but none of the answers really helped me. So my problem is this: I have a bunch of .pov files named, XXXXX000001...., and I want to render them, but the queue thing inside of POV-Ray only lets you render 500 at a time. So, is there a way to render them all automatically? I know the answer is to write a script of some kind, but I don't know a lot about it so if you could give me a step by step instructions I would be grateful. 回答1: Create a POV-Ray .ini file

问题 I've followed this tutorial to export a POV-Ray graphic to a STL file, through Meshlab. I've also tried the export to the OBJ format. Everything seems to work fine from the creation of the POV-Ray graphic to the exporting in Meshlab. But then I've tried to render the graphic in R with the functions readSTL and readOBJ of the rgl package, and the problem is here. In fact, the exported STL file is empty: solid STL generated by MeshLab endsolid vcg So, of course, rgl::readSTL renders nothing in
