The current stack depth. | |
std::stack< mat4f > | spillover |
Any matrices that won't fit on the OpenGL modelview matrix stack get pushed onto this stack. |
OpenGL requires that implementations have a modelview matrix stack with a maximum depth of only 32. Regardless of that, the maximum depth can be expected to vary between implementations, and we don't want nesting of Transform nodes in VRML worlds to be constrained by this limit.
modelview_matrix_stack uses the OpenGL modelview matrix stack until it fills up, at which point any additional matrices that spill over are pushed onto a conventional stack of mat4f.
