## Declaration

public static Matrix4x4 CalculateProjectionMatrix(XRCameraIntrinsics intrinsics, XRCameraParams cameraParams, bool useOpenGLConvention = true)

#### Summary

Returns a transform matrix appropriate for rendering 3D content to match the image
    captured by the camera, using the specified parameters.

#### Returns

The projection matrix.

### Parameters

| Name | Type | Summary |
| --- | --- | --- |
| intrinsics | XRCameraIntrinsics | The intrinsics of the physical camera. |
| cameraParams | XRCameraParams | Presentation params of the virtual camera. |
| useOpenGLConvention | bool | Whether to construct an OpenGL-like projection matrix. |
