I am using SOIL to apply textures to VBOs, without textures i could change the background and display black (default color) vbos easily, but now with textures, openGL is giving an error 1281, the background is black and some textures are not applied. There must be something i didn't understand about applying/loading the textures. BUt the texture IS applied (nothing else is working though), the error is applied when i try to use the shader program however i checked the compilation of these and no problems were written.
Here is the code i use to load textures, once loaded it is kept in memory, it mostly comes from the example of SOIL :
texture = SOIL_load_OGL_single_cubemap(
filename,
SOIL_DDS_CUBEMAP_FACE_ORDER,
SOIL_LOAD_AUTO,
SOIL_CREATE_NEW_ID,
SOIL_FLAG_POWER_OF_TWO
| SOIL_FLAG_MIPMAPS
| SOIL_FLAG_DDS_LOAD_DIRECT
);
if( texture > 0 )
{
glEnable( GL_TEXTURE_CUBE_MAP );
glEnable( GL_TEXTURE_GEN_S );
glEnable( GL_TEXTURE_GEN_T );
glEnable( GL_TEXTURE_GEN_R );
glTexGeni( GL_S, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP );
glTexGeni( GL_T, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP );
glTexGeni( GL_R, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP );
glBindTexture( GL_TEXTURE_CUBE_MAP, texture );
std::cout << "the loaded single cube map ID was " << texture << std::endl;
} else {
std::cout << "Attempting to load as a HDR texture" << std::endl;
texture = SOIL_load_OGL_HDR_texture(
filename,
SOIL_HDR_RGBdivA2,
0,
SOIL_CREATE_NEW_ID,
SOIL_FLAG_POWER_OF_TWO
| SOIL_FLAG_MIPMAPS
);
if( texture < 1 )
{
std::cout << "Attempting to load as a simple 2D texture" << std::endl;
texture = SOIL_load_OGL_texture(
filename,
SOIL_LOAD_AUTO,
SOIL_CREATE_NEW_ID,
SOIL_FLAG_POWER_OF_TWO
| SOIL_FLAG_MIPMAPS
| SOIL_FLAG_DDS_LOAD_DIRECT
);
}
if( texture > 0 ) {
// enable texturing
glEnable( GL_TEXTURE_2D );
// bind an OpenGL texture ID
glBindTexture( GL_TEXTURE_2D, texture );
std::cout << "the loaded texture ID was " << texture << std::endl;
} else {
glDisable( GL_TEXTURE_2D );
std::cout << "Texture loading failed: '" << SOIL_last_result() << "'" << std::endl;
}
}
and how i apply it when drawing :
GLuint TextureID = glGetUniformLocation(shaderProgram, "myTextureSampler");
if(!TextureID)
cout << "TextureID not found ..." << endl;
// glEnableVertexAttribArray(TextureID);
glActiveTexture(GL_TEXTURE0);
if(SFML)
sf::Texture::bind(sfml_texture);
else {
glBindTexture (GL_TEXTURE_2D, texture);
// glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 1024, 768, 0, GL_RGB, GL_UNSIGNED_BYTE, &texture);
}
glUniform1i(TextureID, 0);
I am not sure that SOIL is adapted to my program as i want something as simple as possible (i used sfml's texture object which was the best but i can't anymore), but if i can get it to work it would be great.
EDIT :
After narrowing the code implied by the error, here is the code that provokes it, it is called between texture loading and bos drawing :
glEnableClientState(GL_VERTEX_ARRAY);
//this gives the error :
glUseProgram(this->shaderProgram);
if (!shaderLoaded)
{
std::cout << "Loading default shaders" << std::endl;
if(textured)
loadShaderProgramm(texture_vertexSource, texture_fragmentSource);
else
loadShaderProgramm(default_vertexSource,default_fragmentSource);
}
glm::mat4 Projection = camera->getPerspective();
glm::mat4 View = camera->getView();
glm::mat4 Model = glm::mat4(1.0f);

cout << "ViewID not found ..." << endl;
glUniformMatrix4fv(MatrixID, 1, GL_FALSE, &MVP[0][0]);
glUniformMatrix4fv(ModelID, 1, GL_FALSE, &Model[0][0]);
glUniformMatrix4fv(ViewID, 1, GL_FALSE, &View[0][0]);
drawObject();
