WebAug 4, 2012 · DirectX and OpenGL have different coordinate systems (OpenGL is right, DirectX is left). I know that in the old fixed pipeline functionality, I would use: glScalef(1.0f, 1.0f, -1.0f); This time around, I am working with GLM and shaders and need a compatible solution. I have tried multiplying my camera matrix by a scaling vector with no luck. WebThe origins, goals and key aspects for both Declarative 3D and glTF are investigated in detail using selected examples, with particular focus in how both are designed to harmonize with the supporting ecosystem of WebGL enabled browsers, web standards, best practices and HTML5 frameworks.
