MatrixStack

A matrix stack designed to replace fixed-pipeline matrix stacks. This stack always expose both the top element and its inverse.

int R

R == 3 ||

static if(R == 4)

void perspective(T FOVInRadians, T aspect, T zNear, T zFar);

}

Constructors

this this(size_t depth): Creates a matrix stack. The stack is initialized with one element, an identity matrix.

Destructor

~this ~this(): Releases the matrix stack memory.

Members

Aliases

matrix_t alias matrix_t = Matrix!(T, R, R): Undocumented in source.

Functions

invTop matrix_t invTop()
loadIdentity void loadIdentity(): Replacement for glLoadIdentity.
lookAt void lookAt(vec3!T eye, vec3!T target, vec3!T up): Replacement for gluLookAt.
mult void mult(matrix_t m): Replacement for glMultMatrix.
mult void mult(matrix_t m, matrix_t invM): Replacement for glMultMatrix, with provided inverse.
ortho void ortho(T left, T right, T bottom, T top, T near, T far): Replacement for glOrtho.
perspective void perspective(T FOVInRadians, T aspect, T zNear, T zFar): Replacement for gluPerspective. Warning: FOV is given in radians, unlike the original API.
pop void pop(): Replacement for glPopMatrix.
push void push(): Replacement for glPushMatrix.
rotate void rotate(T angle, Vector!(T, 3) axis): Replacement for glRotate. Warning: Angle is given in radians, unlike the original API.
scale void scale(Vector!(T, R - 1) v): Replacement for glScale.
setTop void setTop(matrix_t m): Sets top matrix. Replaces glLoadMatrix.
top matrix_t top()
translate void translate(Vector!(T, R - 1) v): Replacement for glTranslate.
