MethodDescription
AutoFocusPositions the camera to view all 3D scene objects in the front panel window. Details
Pick ModelCasts a ray through a 3D scene at the Point coordinate and determines which models in the scene intersect with the ray. Details
PickPointGiven an x and y coordinate, casts a ray through the 3D scene and returns the x, y, and z-coordinates of the first object the ray intersects. Details
Projection:FrustumSets coordinates to render the scene in a frustum-shaped view. This projection causes objects farther from the camera to appear smaller. Details
Projection:OrthographicSets coordinates to render the scene in a box-shaped view. The distance of the camera from the objects does not affect the size of the objects in this view. Details
Projection:PerspectiveSets coordinates to render the scene in a frustum-shaped view, where you specify an angle for the horizontal and vertical viewing fields. This projection causes objects closer to the camera to appear larger in size. This method is similar to the Projection:Frustum method. Details
RedrawRedraws the 3D scene in the 3D picture control. Details
Render to ImageReturns an image of the scene. Details
Setup CameraSpecifies the position of the camera relative to the scene. This method modifies the ModelView Matrix. Details
