示例1:
//-------------------------------------------------------------------------
// CREATE LOOK AT creates a look-at matrix for use as a view matrix
matrix4
create_look_at(vector3 &camera, vector3 &target, vector3 &up){
// Builds a look-at style view matrix.
// This is essentially the same matrix used by gluLookAt().
matrix4 out;
vector3 zAxis = camera - target;
zAxis.Normalize();
vector3 xAxis = up.Cross(zAxis);
xAxis.Normalize();
vector3 yAxis = zAxis.Cross(xAxis);
yAxis.Normalize();
out[0] = xAxis.x;
out[4] = xAxis.y;
out[8] = xAxis.z;
out[12] = -xAxis.Dot(camera);
out[1] = yAxis.x;
out[5] = yAxis.y;
out[9] = yAxis.z;
out[13] = -yAxis.Dot(camera);
out[2] = zAxis.x;
out[6] = zAxis.y;
out[10] = zAxis.z;
out[14] = -zAxis.Dot(camera);
out[3] = 0.0f;
out[7] = 0.0f;
out[11] = 0.0f;
out[15] = 1.0f;
return out;
