示例1: lookAt
/// <summary>
/// Build a look at view matrix.
/// transform object's coordinate from world's space to camera's space.
/// </summary>
/// <param name="eye">The eye.</param>
/// <param name="center">The center.</param>
/// <param name="up">Up.</param>
/// <returns></returns>
public static mat3 lookAt(vec2 eye, vec2 center, bool up)
{
// camera's back in world space coordinate system
vec2 back = (eye - center).normalize();
// camera's right in world space coordinate system
vec2 right = up.cross(back).normalize();
if (!up) { right = -right; }
mat3 viewMatrix = new mat3(1);
viewMatrix.col0.x = right.x;
viewMatrix.col1.x = right.y;
viewMatrix.col0.y = back.x;

// Translation in world space coordinate system
viewMatrix.col3.x = -eye.dot(right);
