Model Space

• x, y, z ∈ R
• To next space: Transformation Matrix

World Space

• x, y, z ∈ R
• To next space: Viewing Matrix

View Space

• x, y, z ∈ R
• To next space: Projection Matrix & Perspective Devide

Clip Space(Right-hand)

• -1 ≦ x ≦ 1, -1 ≦ y ≦ 1, -1 ≦ z ≦ 0
• To next space: Right-to-Left Matrix

Clip Space(Device)

• -1 ≦ x ≦ 1, -1 ≦ y ≦ 1, 0 ≦ z ≦ 1
• The default space of OpenGL, Direct3D(Model, View, Projection Matrix are identity)

Screen Space

• 0 ≦ x ≦ Width of window
• 0 ≦ y ≦ Height of window

I add a new space "Right hand clip space" between view space and clip space. It is because that the default space of OpenGL & Direct3D is left hand coordinate.

I use left-hand coordinate to localate the position, but use right-hand to define normal. It offen confuse me.

So, I prefer to put a matrix to make the default space right-hand coordinate.
