Did you know?
WebBy convention, the methods perspective() and lookAt() will assume a right-handed coordinate system. This convention was established for OpenGL and first realized in the OpenGL Utility Library (GLU). JOML follows this convention. In addition, JOML also supports a left-handed coordinate system, as is used by Direct3D’s matrix library. WebThis is the single most important tutorial of the whole set. Be sure to read it at least eight times. Homogeneous coordinates Until then, we only considered 3D vertices as a (x,y,z) triplet. Let’s introduce w. We will now have (x,y,z,w) vectors. This will be more clear soon, but for now, just remember this :

It uses glm_vec3_ortho () to get a UP axis and builds view matrix. You can also _default versions of ortho and perspective to build projection fast if you don’t care specific projection values.
Web14 de nov. de 2011 · I have a problem setting up an orthographic projection matrix with glm::ortho (). The object is a simple quad build by two triangles. The triangles are in the xy-plane with z=0.

Your parameter for aspect ratio might be off also due to the final result not being float. Also, OpenGL uses the glm::orthoLH and glm::perspectiveLH prototypes, which are default.
