COLLADA DOMのViewer用のあれこれをCocoaで利用できないか？

あっちこっちのサンプルを引っ付け合わせてやってみた．
参考: 前回エントリー

１．とりあえずこんな感じのライブラリ周り．

Frameworksのツリー

Other Frameworks下のライブラリはcollada-domに入ってたり作ったりしたヤツ．
Cg.frameworkは前回エントリーでインストールしたヤツで/Library/Frameworksの下．
libz, libxml2は/usr/lib下.

LinkedとOtherの使い分け知らない．Linkedが静的でOhterが動的？

２．とりあえずこんな感じのコード．

MyView.h

#import <Cocoa/Cocoa.h>
#import <OpenGL/CGLRenderers.h>
#import <OpenGL/gl.h>
#import <OpenGL/glu.h>
#import "Crt/CrtRender.h"

@interface MyView : NSOpenGLView 
{
 NSTimer *timer;
}
@end

MyView.mm (拡張子はmm！)

#import "MyView.h"
@implementation MyView
CrtRender   _CrtRender;
- (void) heartbeat
{
 if(![[NSApplication sharedApplication] isHidden]){
  [self setNeedsDisplay:YES];
 }
}

{ 
 NSOpenGLPixelFormatAttribute attribs [] = {
  NSOpenGLPFADoubleBuffer,
  NSOpenGLPFADepthSize, 24,
  NSOpenGLPFAStencilSize, 8,
  0
 };
 NSOpenGLPixelFormat *fmt;
 
 {
  fmt = [[NSOpenGLPixelFormat alloc] initWithAttributes: attribs];
  NSOpenGLContext *preflight = [[NSOpenGLContext alloc] initWithFormat:fmt shareContext:nil];
  [preflight makeCurrentContext];
  [fmt release];
  
  const GLubyte* extensions = glGetString(GL_EXTENSIONS);

 {
  height= 1;      
 }
 glViewport(0, 0, width, height);

３．とりあえずこんな感じの'ヘッダー検索'の設定．

（collada-domが/Users/work/Documents/で展開されたという前提）

４．とりあえずこんな感じのIB．

CustomViewを張ってMyViewに指定．
Autosizingも全部チェックしといて拡大縮小に対応しとくとよいかもw．

５．とりあえずこんな感じの結果．
