Why browser{Chrome 58.0.3029.110 (64-bit) on Windows7} is too slow and crashed finally when i render a map more than 256*256 pixels?

terrain-demo is the code.

when i render a map less than 65536(256*256) pixels, it is ok, please see demo.

but i wanna see a larger range in the same resolution, so pixels increased a lot, such as 512*512, then it failed.

maybe i can not render the whole map at the same time, i must using tiles and do them one by one?

how to do it?

thanks for any response.

Hello nagexiucai,

Have you tried PlaneBufferGeometry instead of PlaneGeometry for your tiles?

Here is the doc for it: https://threejs.org/docs/index.html#api/geometries/PlaneBufferGeometry
