in my Gui to OpenGL code, I'm doing a very naive procedure to copy the World to an OpenGL at every #step. I know that there's many ways to speed this up (I get only 10fps with a saturated core when I do it the simplest way). Suggestsion on how to make the following more efficient? THanks. getLatestImageFromWorld |format form tempTextures| pasteUpFormCanvas ifNil: [^self]. self hide. myPasteUp fullDrawOn: pasteUpFormCanvas. self show. form := pasteUpFormCanvas form. fPUWidth := form width. fPUHeight := form height. tempTextures := WordArray with: (textureIntNames at: 1). ogl glDeleteTextures: 1 with: tempTextures. ogl glBindTexture: GLTexture2d with: (textureIntNames at: 1). ogl checkForError. format := ogl textureInternalFormat. ogl glEnable: GLTexture2d. ogl glTexParameteri: GLTexture2d with: GLTextureMinFilter with: GLLinear. ogl glTexParameteri: GLTexture2d with: GLTextureMagFilter with: GLLinear. ogl glTexImage2D: GLTexture2d with: 0 with: format with: form width with: form height with: 0 with: ogl texturePixelFormat with: ogl texturePixelType with: form bits.
