Detailed Description

Node that specifies texture coordinates which are a linear combination of the object coordinates of the vertex.

This node creates texture coordinates which are a linear combination of the object coordinates of the vertex (xo, yo, zo, wo). A factor can be defined for each component of the texture coordinate (S, T, R, and Q). The generated texture coordinate (S, R, T) at each vertex is:

S = factorS[0] * xo + factorS[1]* yo + factorS[2] * zo + factorS[3] * wo
R = factorR[0] * xo + factorR[1]* yo + factorR[2] * zo + factorR[3] * wo
T = factorT[0] * xo + factorT[1]* yo + factorT[2] * zo + factorT[3] * wo

wo usually equals 1.
