FerruX Projection Matrix

Tool to ease the generation of perspective projection matrices to convert 3D vectors into their 2D projection.

Building the matrix

To build the matrix just create a new Builder and set the properties that will define the projection matrix:

  • near: Position of the near clip in the z-axis. By default 0.0.
  • far: Position of the far clip in the z-axis. By default 1000.0.
  • fov: Field of view in degrees. By default 90.0.
  • width: Frame width. By default 1280.
  • height: Frame height. By default 720.
let matrix = ferrux_projection_matrix::ProjectionMatrixBuilder::new()
               .set_width(1920)
               .set_height(1080)
               .set_fov(100.0)
               .set_far(2000.0)
               .set_near(1.0)
               .build();
println!("{matrix:?}");
