Namespace: OIV.Inventor
Assembly: OIV.Inventor.SbLinear (in OIV.Inventor.SbLinear.dll) Version: 2025.2.0.Release.47655112efc68a70bb943ee3bd5c1e27763923ef
Syntax
public void Perspective(
	float fovy,
	float aspect,
	float nearPlane,
	float farPlane
)

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.
