Hi,
I’m making a point cloud using an edited version of the ofxkinect example. I’m trying to replace the glpoints with 3d objects with textures eg. ofBox with image textures. Can anyone point me in the right direction of how I would go about achieving this? I’m quite new to OF and new to opengl, coming more from processing.
Any help would be greatly appreciated
Here’s the code.
testApp.h
#pragma once
#include "ofMain.h"
class testApp : public ofBaseApp {
public:
void setup();
void update();
void draw();
void keyPressed(int key);
void keyReleased(int key);
void mouseMoved(int x, int y);
void mouseDragged(int x, int y, int button);
void mousePressed(int x, int y, int button);
void mouseReleased(int x, int y, int button);
void windowResized(int w, int h);
void dragEvent(ofDragInfo dragInfo);
void gotMessage(ofMessage msg);
ofImage ofLogo; // the OF logo
ofLight light; // creates a light and enables lighting
ofEasyCam cam; // add mouse controls for camera movement
};
testApp.cpp
#include "testApp.h"
//--------------------------------------------------------------
void testApp::setup(){
ofSetVerticalSync(true);
// this uses depth information for occlusion
// rather than always drawing things on top of each other
glEnable(GL_DEPTH_TEST);
// ofBox uses texture coordinates from 0-1, so you can load whatever
// sized images you want and still use them to texture your box
// but we have to explicitly normalize our tex coords here
ofEnableNormalizedTexCoords();
// loads the OF logo from disk
ofLogo.loadImage("of.png");
// draw the ofBox outlines with some weight
ofSetLineWidth(1);
}
//--------------------------------------------------------------
void testApp::update(){
}
//--------------------------------------------------------------
void testApp::draw(){
ofBackground(0, 0, 0);
float movementSpeed = .1;
float cloudSize = ofGetWidth() / 2;
float maxBoxSize = 100;
float spacing = 1;
int boxCount = 100;
cam.begin();
for(int i = 0; i < boxCount; i++) {
ofPushMatrix();
float t = (ofGetElapsedTimef() + i * spacing) * movementSpeed;
ofVec3f pos(
ofSignedNoise(t, 0, 0),
ofSignedNoise(0, t, 0),
ofSignedNoise(0, 0, t));
float boxSize = maxBoxSize * ofNoise(pos.x, pos.y, pos.z);
pos *= cloudSize;
ofTranslate(pos);
ofRotateX(pos.x);
ofRotateY(pos.y);
ofRotateZ(pos.z);
ofLogo.bind();
ofFill();
ofSetColor(255);
ofBox(boxSize);
ofLogo.unbind();
ofNoFill();
ofSetColor(ofColor::fromHsb(sinf(t) * 128 + 128, 255, 255));
ofBox(boxSize * 1.1f);
ofPopMatrix();
}
cam.end();
}
