The VTT could really benefit to produce cool effects like this if it made full use of the WebGL technology underlying it instead of trying to do 2D canvas implementations for all its features. Making full use of the WebGL technology would not only enable perspectives for isometric maps, but also allow other neat features such as 3D maps, tokens with elevation, and it would still be able to support 2D maps just as easily. Not to mention, the stenciling functions in WebGL could be used to implement a MUCH better version of advanced fog of war. Also, since WebGL uses GPU processing power instead of CPU to render, it could provide performance improvements for many users. There appears to be another suggestion thread for isometric grids. I'd recommend everyone put their votes there: <a href="https://app.roll20.net/forum/post/1295021/slug%7D" rel="nofollow">https://app.roll20.net/forum/post/1295021/slug%7D</a>
