GSDP:GAM100/CProcessing/mat3 t



A mat3_t (3D matrix type) is a structure that can hold nine float values. This is used for linear algebra and transformation, but can be used for any purpose that requires nine float values. There are a series of operations that can be done using a 3D matrix that are also provided.


void update() 
    // create a transform and set it to initialized values
    mat3_t transform = mat3();

    // make the matrix a translation transform by (100, 100)
    transform = mat3_translate( (vec2_t) { 100, 100 } );

    // create a vec2_t position
    vec2_t position;
    position.x = 100;
    position.y = 100;

    // apply that matrix to the point and store it in the position
    position = mat3_mult_vec2(transform, position);
