Problème multitexturing automatique
Bonjour j'aimerais pouvoir texturé un objet avec plusieurs textures(ambiant, diffuse...). Le soucis est que cela ne fonctionne pas.
Voici le code opengl :
Code:

void Material::activeTextures()
{
unsigned int i = 0, j = 0;
//active and bind textures
for (i = 0; i < textures_ambiant.size(); i++)
{
glActiveTexture(GL_TEXTURE0 + i);
this->textures_ambiant[i]->bind();
glUniform1i(glGetUniformLocation(programID, ("samplerAmbiantTexture" + std::to_string(i)).c_str()), i);
j++;
}
for (i = 0; i < textures_diffuse.size(); i++)
{
glActiveTexture(GL_TEXTURE0 + i + j);
this->textures_diffuse[i]->bind();
//std::cout << ("samplerDiffuseTexture" + std::to_string(i)).c_str() << std::endl;
glUniform1i(glGetUniformLocation(programID, ("samplerDiffuseTexture" + std::to_string(i)).c_str()), i + j);
j++;
}
for (i = 0; i < this->textures_specular.size(); i++)
{
glActiveTexture(GL_TEXTURE0 + i + j);
this->textures_specular[i]->bind();
glUniform1i(glGetUniformLocation(programID, ("samplerSpecularTexture" + std::to_string(i)).c_str()), i + j);
}
} |
et le render :

void DefaultMaterial::render(Model *model)
{
//UNIFORMS
//this->M *= glm::rotate(0.005f, glm::vec3(0, 1, 0));
this->Normal_Matrix = glm::transpose(glm::inverse(this->M));
//set the uniform variable MVP
glUniformMatrix4fv(this->MID, 1, GL_FALSE, &M[0][0]);
glUniformMatrix4fv(this->NMID, 1, GL_FALSE, &Normal_Matrix[0][0]);
glUniform1fv(this->compl.ambiantID, 1, &(compl.ambiant));
glUniform1fv(this->compl.diffuseID, 1, &(compl.diffuse));
glUniform1fv(this->compl.specularID, 1, &(compl.specular));
//OPTIONS
//Enable culling triangles which normal is not towards the camera
glEnable(GL_CULL_FACE);
// Enable depth test
glEnable(GL_DEPTH_TEST);
//TEXTURES
this->activeTextures();
//BUFFERS
for (int i = 0; i < 4; i++)
{
//bind UBO buffer light
glBindBufferBase(GL_UNIFORM_BUFFER, i, this->scene->getCollector()->getLightUBO(i)->getID());
//bind UBO lighting with program shader
glUniformBlockBinding(this->programID, this->block_index_lights[i], i);
}
//bind UBO buffer camera
glBindBufferBase(GL_UNIFORM_BUFFER, 4, this->scene->getCamUBO()->getID());
//bind UBO camera with program shader
glUniformBlockBinding(this->programID, this->block_index_camera, 4);
//RENDER
//render model
model->render();
//RELEASE
this->releaseTextures();
//glBindBufferBase(GL_UNIFORM_BUFFER, 0, 0);
} |
et dans le fragment shader:
j'utilise cette variable: juste une texture "uniform sampler2D samplerDiffuseTexture0;"
Sauf que le résultat est noir, et du coup ne fonctionne pas.
Quelqu'un aurait t il une idée?
Je vous remercie d'avance :)
