C++ (Cpp) _math_matrix_scale Examples

Example #1

File: matrix.c Project: mariuz/haiku

/**
 * Multiply the current matrix with a general scaling matrix.
 *
 * \param x x axis scale factor.
 * \param y y axis scale factor.
 * \param z z axis scale factor.
 *
 * \sa glScalef().
 *
 * Flushes the vertices and calls _math_matrix_scale() with the top-most
 * matrix in the current stack and the given parameters. Marks
 * __GLcontextRec::NewState with the dirty stack flag.
