In the image above, the camera’s world transform is shown in the left pane and the view from the camera is shown on the right. This matrix is the inverse of the camera’s transformation matrix.Ĭamera World Matrix vs View Matrix – The model of the car is from Nate Robin’s OpenGL tutorials ( ).

The View Matrix: This matrix will transform vertices from world-space to view-space.The Camera Transformation Matrix: The transformation that places the camera in the correct position and orientation in world space (this is the transformation that you would apply to a 3D model of the camera if you wanted to represent it in the scene).In order to understand this correctly, we must think in terms of two different things: In a computer program the camera doesn’t move at all and in actuality, the world is just moving in the opposite direction and orientation of how you would want the camera to move in reality. You can get a different view of the car by moving your camera around it and it appears that the scene is moving when you view the image through your camera’s view finder. Imagine you are holding a video camera, taking a picture of a car. Don’t be mistaken and think that these two things are the same thing! The view matrix is used to transform a model’s vertices from world-space to view-space. The world transformation matrix is the matrix that determines the position and orientation of an object in 3D space. The reason for this is the abstract nature of this elusive matrix. Understanding how the view matrix works in 3D space is one of the most underestimated concepts of 3D game programming. 9 Converting between Camera Transformation Matrix and View Matrix.2.1 Memory Layout of Column-Major Matrices.
