从3dStudioMax导入模型到THREE.js

我知道THREE.js有来自各种3D图形格式的导入器。

是否有一种适合显示在三维工作室Max中创建的模型的导入器？如果没有，是否有一种将3D Studio Max模型转换为可以在THREE.js中导入的格式的方法？

顺便说一下，这将是一个非常适合在http://area51.stackexchange.com/proposals/5022/3d-graphics-modeling-applications上提问的问题。 - cdiggins

以下是一个 MAXScript 脚本，可以将选定对象的网格转换为 JSON 格式。在此帖子发布时，它可在 Google 代码托管的 3ds Max 开发者社区的 SVN 中获取。

tmesh = snapshotAsMesh selection[1]
out_file = createfile "$scripts\\output.json

num_faces = tmesh.numfaces
num_verts = tmesh.numverts 

fn PrintPoint pt = (
 format "%, %, %, " pt.x pt.y pt.z to:out_file
)   

fn PrintPointUV pt = (
 format "%, %, " pt.x pt.y to:out_file
)   

fn PrintPointInt pt = (
    x = int(pt.x) - 1
    y = int(pt.y) - 1
    z = int(pt.z) - 1
    format "%, %, %, " x y z to:out_file
)   

format "{\n" to:out_file

-- Vertex Positions 
-- format "    \"vertexPositions\" : [" to:out_file
format "    positions : [" to:out_file
for i = 1 to num_verts do
(
 vert = getVert tmesh i
 PrintPoint vert
)
format "],\n" to:out_file

-- Vertex Normals
-- format "    \"vertexNormals\" : [" to:out_file
format "    normals : [" to:out_file
for i = 1 to num_verts do
(
  vert = getNormal tmesh i
  PrintPoint vert
)
format "],\n" to:out_file

-- Vertex Texture Coordinates 
-- format "    \"vertexTextureCoords\" : [" to:out_file
format "    uv : [" to:out_file
for i = 1 to num_faces do
(
    -- Iterate over faces 
    tvface = getTVFace tmesh i
    for j = 1 to 3 do (
        -- Get a specific texture vertex
        tvert = getTVert tmesh tvface[j]        
        PrintPointUV tvert
    )
)
format "],\n" to:out_file

-- Face Indexes
-- format "    \"indices\" : [" to:out_file
format "    indices : [" to:out_file
for f = 1 to num_faces do
(
   face = getFace tmesh f
   PrintPointInt face
)
format "],\n" to:out_file

format "}" to:out_file

close out_file
delete tmesh
edit out_name
