void G3_PerspectiveW( fx32 fovySin, fx32 fovyCos, fx32 aspect, fx32 n, fx32 f, fx32 scaleW, MtxFx44 * mtx );
fovySin | Sine value of the field-of-view angle (view angle) in y-direction/2 |
fovyCos | Cosine value of the field-of-view angle (view angle) in y-direction/2 |
aspect | Ratio of width of view field to height of view field (aspect ratio: width/height of the field of view) |
n | Distance from eyepoint to the near clip plane |
f | Distance from eyepoint to the far clip plane |
scaleW | Fine adjustment parameter for the view volume |
mtx | The pointer to a 4x4 matrix. |
None.
This function sets the Matrix mode to the Projection mode. This function also sets the Frustum matrix as the current matrix. If mtx
is not NULL
, then the Frustum matrix is also set in *mtx
. This function uses the Divider. The diagram shows the matrix that is set.
