If all goes to plan then Qt3D will be released along with Qt 5.2. Although not part of the Qt3D module, the improvements described here form a good part of the foundations upon which we will build the Qt3D renderer. I know many people have been asking about the status of Qt3D. We are very keen to see OpenGL support in Qt continue to improve and will continue to work to do so. Some of the items on the radar include Textures, Texture Images, Samplers, Occlusion Queries, Transform feedback objects, Uniform Buffer Objects, Shader Storage Buffer Objects and Shader Program Pipeline Objects, Object labels for debug output #COMPUTE SHADER EXAMPLE OPENGL 4.3 CODE#There is still much to do and we will continue adding more enablers to make it easier and safer to write OpenGL code as we move towards Qt 5.2. For the futureĪs we have seen, Qt 5.1 adds a great deal new functionality and enablers around OpenGL. The availability of Geometry, Tessellation stage and Compute shaders really opens the doors for some interesting effects and order of magnitude improvements in performance over what is possible with plain OpenGL 2.x. Tessellation Control and Tessellation Evaluation Shaders (requires OpenGL 4.0)Īs long as your platform has support for the required OpenGL version, then Qt 5.1 will work there.Qt 5.1 will include support for all shader stages supported by OpenGL: In Qt 5.0 the QOpenGLShader and QOpenGLShaderProgram classes only had support for Vertex and Fragment shaders. Earlier articles in this series are available at: This article concludes our series on what is new in Qt 5.1 with respect to OpenGL.
