void Perspective(
float fovy,
float aspect,
float nearPlane,
float farPlane
)
member Perspective :
fovy : float32 *
aspect : float32 *
nearPlane : float32 *
farPlane : float32 -> unit
Parameters
- fovy
- Type: SystemSingle
The field of view angle, in radians, in the y-direction. - aspect
- Type: SystemSingle
The aspect ratio that determines the field of view in the
x-direction. The aspect ratio is the ratio of x (width) to y (height). - nearPlane
- Type: SystemSingle
The distance from the viewer to the near clipping plane (always positive). - farPlane
- Type: SystemSingle
The distance from the viewer to the far clipping plane (always positive).
Remarks
The parameters are the same as for the OpenGL gluPerspective() routine,
except that the field fovy is specified in radians.
