Mat2
2x2 floating point matrix
Declaration
mat2 aMat2 = mat2(1.0, 0.0, // 1. column
0.0, 1.0); // 2. column
mat2 bMat2 = mat2(1.0);
mat2 cMat2 = mat2(aVec2, bVec2);
mat2 dMat2 = mat2(aVec3, aFloat);
Description
mat2 data type is compose for a 2x2 matrix of floating point. As you can see above, can be initialize in different ways:
-
Providing a value for each component column by column.
-
Providing one value that is used for the components on the main diagonal.
-
Providing a combination of vectors and scalars.
In the same way data can be accessed component-wise or column by column:
mat2 aMat2;
aMat2[1][1] = 1.0;
float aFloat = aMat2[1][1];
aMat2[0] = vec2(1.0);
vec2 aVec2 = aMat2[0];
