How to use assimp load 3D model and use shader to render it

beginners
#1

I saw all the examples but not found a project can help me .
I want to use shader on 3D penguin project. can any body help… …thanks for show me some codes

#2

Which examples did you look at? and what did you try? show us some of your attempts :wink:

ofShader is applied to a mesh like ofMaterial.

// in your ofApp.h
ofMaterial material;
// in your ofApp.cpp

material.begin();
mesh.draw();
material.end().

Same syntax for ofShader

// in your ofApp.h
ofShader shader;
// in your ofApp.cpp

shader.begin();
mesh.draw();
shader.end().

Have a look at the shader chapter on the ofBook http://openframeworks.cc/ofBook/chapters/shaders.html , and look for the word ofShader and ofMaterial in your example folder.

.3DModelLoaderExample this one

ofEnableDepthTest();

light.enable();

cam.begin();
ofColor(255,255);
if (bUsingMesh){
	// draws the ply file loaded into the mesh is you pressed 6
	meshNode.transformGL();
	mesh.draw();
	meshNode.restoreTransformGL();
} else {
	// draws all the other file types which are loaded into model.
	model.drawFaces();
}
cam.end();

light.disable();

ofDisableDepthTest();

I want to change that code . it was not use shader and I don’t know how.
I just learn 3D knowledge about 1month before that I write shader on cocos2dx …2D picture :frowning:

can u give me some reference :frowning:

Can u tell me which example can help …
