Graphics / Loading SFML Textures in Opengl
« Last post by Bogdan on December 08, 2024, 08:57:10 pm »Hello there,
I've encountered a new problem with sfml/opengl loading of textures. There is much outdated info on the net about opengl and sfml...
As the example below uses a different library, I wanted to ask: How to do the texture loading part just with SFML and Opengl. If I try using sf::Texture, it always says that it's incompatible wit Gluint type.

unsigned int texture;
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
// set the texture wrapping/filtering options (on the currently bound texture object)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR_MIPMAP_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
// load and generate the texture
int width, height, nrChannels;
unsigned char *data = stbi_load("container.jpg", &width, &height, &nrChannels, 0);
if (data)
{
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, data);
glGenerateMipmap(GL_TEXTURE_2D);
}
else
{
std::cout << "Failed to load texture" << std::endl;
}
stbi_image_free(data);
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
