spherical cow

multiply the sh coefficient of the radiation degree and the sh coefficient of the illumination to obtain the final radiation degree, add the image as a parameter to the illumination model to obtain a diffuse image with a low frequency, soft shadow, or even interreflection. Of course, the actual situation is far from that simple, especially the rotation of the sh coefficient. Currently, d3dxshrotate in d3dx only supports up to 6 levels of sh.

Spherical (spherize) filterSpherical filter is a spherical effect of the image by polar coordinate transformation.The code is as follows://///Pinch FilterSource image.The X position of sun.The Y position of sun.The result image.Private Bitmap spherizefilterprocess (Bitmap srcbitmap, int cenx, int ceny){Bitmap a = new Bitmap (SRCBITMAP);int w = a.width;int h = a.height;int radius = 0;Bitmap DST = new Bitmap

DescriptionThere is a spherical space generator capable of producing a hard sphere in n-dimensional space. Now that you are trapped in this n-dimensional sphere, you only know the coordinates of the n+1 points on the sphere, and you need to determine the spherical coordinates of the n-dimensional sphere as quickly as you can to destroy the sphere space generator.InputThe first line is an integer, N.
