OpenGL GL_RGB texture form isn t working on Ri (GL_RGBA work grand)
原标题:OpenGL GL_RGB texture format isn t working on iOS (GL_RGBA works great)

Hello people of the wasteland :

简言之:L_RGB内部文本处理表存在问题。

In my application I try to save some memory by using GL_RGB instead of GL_RGBA as an internal format. I m using the next code piece to achieve this. Nothing else is changed.

glTexImage2D(_textureTargetType, 
     0, 
     GL_RGB,            // pixel internalFormat
     texWidth,          // image width
     texHeight,         // image height
     0,             // border
     GL_RGBA,           // pixel format
     GL_UNSIGNED_BYTE,      // pixel data type
     bitmapData);

在澳门特区,这些变化无常,没有问题。 但就Si,特别是4.3(OpenGL ES2.0)而言,它给了我GL_VALINID_OPERATION。 我每次都试图用这一案文作成文.。 由于除了这一格式之外没有任何变化,我认为问题与开放式信用证ES2.0不一致。 这只是我的猜测,我不 g。

这在模拟器或正感触4型基因中都是如此。

Thank you for any reasonable suggestion.

根据这些文件,“internalformat必须匹配format。 文本处理过程中不支持格式之间的转换。 见。 开放 GL没有这种限制,因此,该守则将涉及MacOS,但不限于LES。
