Mobileįinally, the end result is also good for OpenGLES (usually on mobile, though it also works on desktop if you want). So you can test how does editor behave on ancient OpenGL implementations, just run it like this: castle-editor -capabilities=force-fixed-function.

View3dscene and the CGE editor itself also support these options. We also have a new menu items in CGE editor to easily set it “Run -> Run Parameters -> …”. It is available in all CGE applications ( TCastleApplication.ParseStandardParameters handles it, and it is called from CastleAutoGenerated unit). capabilities=force-fixed-function or -capabilities=force-modern). We have a new command-line option -capabilities=automatic (or The renderer was really tested with actual OpenGL 1.1 implementation available on some Windows 2016 servers 🙂 Switching between modern and ancient OpenGL Some modern rendering features are not available (like PBR or shadow maps), but simple games will manage. Rendering on such old systems supports unlit or Phong lighting. However, if the provided OpenGL version will be low ( Run Parameters -> Force Ancient Rendering Context (–capabilities=force-fixed-function)”, then run as usual (F9 or click the button). Later versions also imply some nice things, e.g.

As mentioned above, OpenGL >= 2 implies a lot of things (VBO, shaders) and we will use them. If it has a new OpenGL version - we will actually use only the new API, just like from “core” profile. Uses shadow samplers following OpenGL(ES) core Uses image formats without luminance, instead we use texture swizzle. Or in CGE editor click “Run -> Run Parameters -> Force Modern Rendering Context (–capabilities=force-modern)”.Īutomatically converts quads to triangles as modern OpenGL(ES) API don’t support quads.

Or pass command-line option -capabilities=force-modern. To force using it, set TGLFeatures.RequestCapabilities to rcForceModern. So we have implemented a code path using 100% “core profile” OpenGL 3.3 context (using deprecated stuff is prohibited). So for many things, we can just assume that modern OpenGL will have them in “core”. If we have shaders, we know we have shaders from “core”, and we initialize them with the same code everywhere. We have now much better support of new OpenGL features. We have made a few significant refactors of our low-level OpenGL(ES) code, to support better both modern GPUs, ancient GPUs and mobile GPUs.
