mat3()
Description
Create a Mat3 default matrix. This is the same as the Mat3 identity matrix that you get from calling mat3_identity().
Example
Mat3 default_m;
Mat3 identity_m;
void init()
{
textFont(defaultFont, 30.0f);
fill(color(0, 0, 0, 255));
default_m = mat3();
identity_m = mat3_identity();
}
void update()
{
background(color(255, 255, 255, 255));
// Print out the default matrix
text("Default: ", 0, 30);
char matrix[128] = {0};
sprintf_s(matrix, 128,"[%.0f, %.0f, %.0f]\n[%.0f, %.0f, %.0f]\n[%.0f, %.0f, %.0f]",
default_m.m00, default_m.m01, default_m.m02,
default_m.m10, default_m.m11, default_m.m12,
default_m.m20, default_m.m21, default_m.m22);
textBox(matrix, 175, 30, 200);
// Print out the identity matrix
text("Identity: ", 0, 150);
sprintf_s(matrix, 128, "[%.0f, %.0f, %.0f]\n[%.0f, %.0f, %.0f]\n[%.0f, %.0f, %.0f]",
identity_m.m00, identity_m.m01, identity_m.m02,
identity_m.m10, identity_m.m11, identity_m.m12,
identity_m.m20, identity_m.m21, identity_m.m22);
textBox(matrix, 175, 150, 200);
text("They are the same!", 0, 300);
}
