Hi Chris, There is too many unknowns for the rest of us to be know what is going wrong with this latest issue - only you have your code and models, and can view what is happening first hand and use a debugger to step through what is happening.
The best we can do is provide general recommendations. For moving graphics on and off screen you have a range of options - your could alter the Camera view or projection matrix, or even the viewport, or even place a transform above the scene graph that you want to animate, so all of these options are viable. Which is best is probably down to how you manage things, conceptually I'd say animating things on/off screen is a viewer level operation, so I'd do it at the Camera level rather than a transform within the scene graph. Personally I'd alter the view matrix, but this is just a general preference. Robert. On 20 November 2014 14:49, Chris Hidden <[email protected]> wrote: > Ran into a new problem.
