问题 How to write a CGA shader that limit the palette to 4 colors and match the original colors with those (cyan, magenta, black, white)?? I'm working on Game Maker Studio Professional, that actually allows the using of shaders writing vertex and fragment code I already asked this question also in the yoyogames community and in the openGl forum someone answered me with this : varying vec2 v_vTexcoord; varying vec4 v_vColour; const mat3 rgb_to_wcm = mat3(1,-1, 0, 1, 0,-1, -1, 1, 1); void main() {

When I have two orientation quaternions, how do I find the rotation quaternion needed to go from one to the other?

问题 I'm using quaternions in my game, and I'm wondering how, when I have two orientation quaternions, I can get the rotation quaternion needed to go from the first one, q1, to the second one, q2. I'm self taught, so there may be obvious solutions missing from my vocabulary. In equations, what I'm doing when I rotate from the first one to the other is as follows: q2 = r * q1 However, now r is the unknown. Do the rules of algebra count here too? If that's the case, I'd end up dividing a quaternion

问题 I know that this is a very common error, but it's the first time I've encountered it when trying to write a file. I'm using networkx to work with graphs for network analysis, and when I try to write into any format: nx.write_gml(G, "Graph.gml") nx.write_pajek(G, "Graph.net") nx.write_gexf(G, "graph.gexf") I get: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 2, in write_pajek File "/Library/Python/2.7/site-packages/networkx/utils/decorators.py",
