General Information

Camera struct. Makes movement arround viewport possible. Always uses projection matrix and moves arround a sphere given a target.

Fields

• camera_position - Camera position from original coordinate system (world coordinate system).
• camera_target - Normally set to (0,0,0) but can change. What camera points at.
• view_matrix - How camera ends up viewing object.
• active_view_change - Wether we can change view matrix. Normally used in callback functions inside loop.
• projection_matrix - Perspective matrix to see final results in screen.
• up_vector - Vector to create a coordinate system for camera relative to it’s position (position ends up in (0,0,0) in default mode).
• camera_sensitivity - How much should camera get close when zooming and moving arround objective.
• theta - y axis - position angle to move camera.
• phi - xz plane - position angle to move camera.
• radius - how far away camera is from object.
