我需要将bin文件转换为opengl纹理并将其显示在mfc中

本文介绍了我需要将bin文件转换为opengl纹理并将其显示在mfc中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我想将bin文件转换为opengl纹理并在MFC中显示它。我使用下面的代码。我尝试了glTexParameterf而不是glTexParameteri，GL_LINEAR而不是GL_NEAREST并且使用了GL_REPEAT而不是GL_CLAMP但没有用。 我尝试了什么： I want to convert a bin file into opengl texture and display it in MFC. I used the below code. I tried glTexParameterf instead of glTexParameteri,GL_LINEAR instead of GL_NEAREST and used GL_REPEAT instead of GL_CLAMP but no use.What I have tried:char* chBinBuffer = NULL; BYTE* Bitmap_Data = NULL; chBinBuffer = new char[1280 *690 * 4];Bitmap_Data = new BYTE[1280 *690 * 4 ]; TCHAR tchFileName[MAX_PATH]; swprintf_s(tchFileName, _T("D:\\Bin Files\\InputData_1280_690.bin")); FILE* pFile = NULL; _wfopen_s(&pFile, tchFileName, _T("rb")); if(NULL != pFile) { fread(Bitmap_Data, 1280 *690 * 4 * sizeof( unsigned char ), 1, pFile); fclose(pFile); } GLuint glTexture; glEnable(GL_TEXTURE_2D); glGenTextures(1, &glTexture); glBindTexture(GL_TEXTURE_2D, glTexture); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_MODULATE); // select modulate to mix texture with color for shading // when texture area is small, bilinear filter the closest mipmap glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST ); // when texture area is large, bilinear filter the original glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST ); // the texture wraps over at the edges (repeat) glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP ); glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP ); // // build our texture mipmaps /* gluBuild2DMipmaps( GL_TEXTURE_2D, 3, 1280, 690, GL_RGBA, GL_UNSIGNED_BYTE, Bitmap_Data );*/ glTexImage2D(GL_TEXTURE_2D,0, GL_RGBA8, 1280, 690, 0, GL_RGBA, GL_UNSIGNED_BYTE, Bitmap_Data); //glTexSubImage2D( GL_TEXTURE_2D, 0, 0, 0, 1280, 690, GL_RGBA, GL_UNSIGNED_BYTE, Bitmap_Data ); delete [] chBinBuffer;delete[] Bitmap_Data; //glDeleteTextures( 1, &glTexture ); 但我没有得到任何输出。请帮助我。But i didnt get any output.
