Enter instanced rendering. An Instance is a single occurence of the model that you want to render (in our case, a soldier). Instanced rendering means that we 4 Feb 2014 When the first copy of the vertices is sent to OpenGL, gl_InstanceID will be zero. It will then be incremented once for each copy of the geometry The test setup uses 64000 instances, and the geometry includes cubes in vertex arrays (VA) or vertex buffer objects (VBO), and low (~80 tris) and high (~230 tris)2 Jan 2016 8 Aug 2013 Instancing became a core feature of OpenGL starting with version 3.1 back in 2009, Instancing solves this by allowing you to tell the driver: 'Hey, I'd like to draw this piece of geometry 1000 times'. . -related tutorials I found Learn OpenGL . com provides good and clear modern 3.3+ OpenGL tutorials with Instancing is a technique where we draw many objects at once with a single 12 Nov 2013 20 Jan 2018 Use geometry shaders. Not in the scope of this tutorial, mostly because 50% of the computers don't support this. Use instancing. Not available on ALL computers 22 Apr 2013 Learn how to identify all of the rendering primitives available in OpenGL, initialize and populate data buffers for use in rendering geometry, and
