WebPanorama to Cubemap Convert a 360° panorama to six cube faces. Upload Upload a panoramic image: The image should be formatted with the equirectangular projection. The image should have an aspect ratio of 2:1 (the width must be exactly twice the height). A cubemap will be generated from your image. Settings WebApr 16, 2015 · Imaging a sphere with lines of latitude and longitude on it, and a cube surrounding it. Now projecting from the point at center of the sphere produces a distorted grid on the cube. Mathematically, take polar coordinates r, θ, ø, for the sphere r=1, 0 < θ < π, -π/4 < ø < 7π/4. x= r sin θ cos ø; y= r sin θ sin ø; z= r cos θ
Webit can access it in my fragment shader via uniform samplerCube Cubemap. I'm calling the below function like so: cubeMapTexture = renderToCubeMap (150, GL_RGBA8, GL_RGBA, GL_UNSIGNED_BYTE); Now, I realize in the draw loop below that I'm not changing the view direction to look down the +x, -x, +y, -y, +z, -z axis.
