Currently the jme3-lwjgl library is used by default, both in the SDK and in jme3-examples. Instead, JOML post-multiplies the projection and view transformations by the Matrix4f they are invoked on. ![]() However, unlike the methods in LWJGL 2, JOML does not interface with OpenGL to multiply the matrices. LWJGL 3 is a fresh start and LWJGL 2 is its predecessor. The matrix operations implemented in the GLU class are part of the Matrix4f in JOML. The same table for vector operations in Vector4f: LWJGL 2 (cube versus quad), shader program (3D vs 2D post-processing) and textures. These are listed in the following table: LWJGL 2 OpenGL is a well-known standard for generating 3-D as well as 2-D graphics. Some Matrix4f operations have different names in JOML. LWJG元 is much newer relatively speaking, consequentially, you're far more likely to find more tutorial resources on 2 than 3. In JOML the position will not be changed! LWJG元 is based on the GLFW library, so any documentation for GLFW will usually hold true with LWJG元 2nd. In LWJGL 2 the position of the FloatBuffer will be incremented by load and store operations. One important difference is the handling of NIO FloatBuffers when getting values from or writing values into a FloatBuffer. JOML uses a very similar design compared to LWJGL 2's util vecmath classes, by providing instance methods writing the result back into the same object, and instance methods accepting a destination parameter.Īlso, methods such as rotate(), translate() and scale() post-multiply their respective transformations to the current matrix values. So if you are using LWJGL 2 and especially its "util" jar with the classes in the included vector package, you can migrate easily to JOML. After hundreds of commits including additions, updates, performance improvements and bug fixes, we are proud to announce the release of LWJGL 3.1.0. This article is for people who are currently using LWJGL 2 and wanting to switch to LWJGL 3. Contains bindings to Vulkan, a new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in a wide variety of devices from PCs and consoles to mobile phones and embedded platforms. ![]()
