CameraProjMode

CameraProjMode (camera, mode)

mode - projection mode:

• 0: no projection - disables camera (faster than HideEntity)
• 1: perspective projection (default)
• 2: orthographic projection

Description:

Sets the camera projection mode.

The projection mode is the the technique used by Blitz to display 3D graphics on the screen. Using projection mode 0, nothing is displayed on the screen, and this is the fastest method of hiding a camera. Using camera projection mode 1, the graphics are displayed in their 'correct' form - and this is the default mode for a camera. Camera projection mode 2 is a special type of projection, used for displaying 3D graphics on screen, but in a 2D form - that is, no sense of perspective will be given to the graphics. Two identical objects at varying distances from the camera will both appear to be the same size. Orthographic projection is useful for 3D editors, where a sense of perspective is unimportant, and also certain games.

Use 'CameraZoom' to control the scale of graphics rendered with orthographic projection. As a general rule, using orthographic projection with the default camera zoom setting of 1 will result in graphics that are too 'zoomed-in' - changing the camera zoom to 0.1 should fix this.

One thing to note with using camera project mode 2, is that terrains will not be displayed correctly - this is because the level of detail algorithm used by terrains relies on perspective in order to work properly.
