Class Mat23

Namespace

Vintagestory.API.MathTools

Assembly

VintagestoryAPI.dll

2x3 Matrix

• A mat2d contains six elements defined as:
• [a, b,
• c, d,
• tx,ty]
• This is a short form for the 3x3 matrix:
• [a, b, 0
• c, d, 0
• tx,ty,1]
• The last column is ignored so the array is shorter and operations are faster.
