\"\"<\/a><\/p>\n

Converted this Marching Cubes(three.js\/webgl)<\/a> to Unity Javascript<\/p>\n

– Added image#3 (using perlin noise to generate caves)
\n– Added profiler image, fatal error image, neighbour chunk connection problem..
\n– Changed default unity arrays to Lists(), much faster now
\n– Added some new images
\n– Now digging the ground possible with “mining laser” (its quite slow on higher resolution, because of the mesh collider updates..)<\/p>\n

\ncoming later.. (Current test version source is available for those who donate any amount<\/del> – minimum 1usd – pls.)<\/em><\/p>\n

Image#1 : First test, failed because of 1 typo & some variables were as ints.. hmm, would the int version be much faster?<\/p>\n

Image#3: Using 3D Perlin Noise<\/p>\n

\"\"<\/p>\n

Image#4: Bigger caves<\/p>\n

\"\"<\/p>\n

—<\/p>\n

Image#5: deep profiler (mesh collider update removed from here..it was too slow, now Perlin noise takes most of the time..)<\/p>\n

\"\"<\/a><\/p>\n

\nImage#6: After flying inside the caves for a while got this fatal error.. (had forgotten new Mesh(); inside the loop..)<\/p>\n

\"\"<\/a><\/p>\n

—<\/p>\n

Image#7: Trying to connect neighbour chunks.. Some parts are not connected, some are. *Fixed: Had wrong world pos value for the next chunk<\/p>\n

\"\"<\/a><\/p>\n

—<\/p>\n

Image#8: Somehow need to fix the stretching textures.. now each face is UV(0,0|0,1|1,1)..<\/p>\n

\"\"<\/a><\/p>\n

—<\/p>\n

Image#9: Now walls\/border holes are capped<\/p>\n

\"\"<\/p>\n

—<\/p>\n

Image#10: Now digging is possible (just some random “out of range” errors still..)<\/p>\n

\"\"<\/p>\n

—<\/p>\n

Image#11: Now you can sculpt the mesh (add\/remove), make caves etc. (Need to add adjustable brush size and somehow save the mesh to editor?)<\/p>\n

\"\"<\/p>\n

Image#12: with DX11 Tesselation shader<\/p>\n
