Irrlicht Engine

I am still having problems getting this to work. I will post my main method, my shader callback and my shader programs. It is not doing nearly what it should. I believe the cubs should be red and half transparent. Shader.h /* * shader.h * VisApp2 * * Created by Jeff Paddon on 11/05/07. * Copyright 2...

Yes, I understand that I cannot assign a variable in the cpu, but I don't think I understand how I use the variable I define as uniform. eg uniform vec4 color void main(){ gl_FragColor = color; } Now in main.cpp do I just do something like this setPixalShaderConstant(color, 'value', 4) will that ass...

Ok so this is what I have so far, it is not working though, can anyone see why? Vertex Shader: void main() { vec3 normal, lightDir; vec4 diffuse; float NdotL; normal = normalize(gl_NormalMatrix * gl_Normal); lightDir = normalize(vec3(gl_LightSource[0].position)); NdotL = max(dot(normal, lightDir), 0...

ok I think I understand... so how do I, then, load the shaders if I do not use the shader callback class (it seems I do not need it for my purposes)

Hey all, I am using the Irrlicht3D engine to develop a Visualization application for my current research. However, since I am developing on a mac I am using OpenGL rendering with Irrlicht. I have written my own, basic shader to use with irrlicht but I am not quite sure how I communicate from within ...

Yea it won't be. So I have decided to learn GLSL. Upon thinking about it some of the future plans for my VisApp will require some sort of computationally intensive graphics and knowing how to program my own shaders will prove useful. I suppose looking for an easy way out is not always the answer hah...

Hey all, I was wondering, I want to take the irrlicht primatives (Sphere scene node and Cube scene node) and change their color and/or transparencies without using shaders or textures in an attempt to speed up my program and also because I do not know how to write shaders. If this wasn't possible do...

Yea I just figured that was what you meant after I poseted.

That is definatly what is wrong because i am using the irrlicht-1.0 sdk that is on this site. I think I got it now, thanks a lot.

I am using the following headers:

#include <irrlicht.h>
#include <iostream>
#include <OpenGL/OpenGL.h>
#include <sys/stat.h>

Is there another header I should include when using these primitives?

I don't know if this is a Mac thing or not, but I am using the Irrlicht 1.3 library I obtained off this site, but when I try and compile the following code I get this error: error: 'class irr::scene::ISceneManager' has no member named 'addSphereSceneNode' Here is my code: int main() { ICameraSceneNo...

Hey all, I am still attempting to port one of my visualization applications that implements Irrlicht to my Mac. However, my glut primitives will not work the same for me on the mac as they did under linux. This code worked fine under linux. I get nothing plotted on screen though. Essentially what is...

Hey all, I followed the MacOSX X-Code tutorial to a tee, but when I attempt to build I get the following error. libMacOSX.a(png.o) has local relocation entries in non-writable section (__TEXT,__text) Command /usr/bin/gcc-4.0 failed with exit code 1 The only difference in what I did and what the tuto...

Hey All, I have a program which reads in coordinates of cubes (essentially) from various external ASCII files. What is supposed to happen is the program reads in this data, then plots the cubes as required. Essentially each file is a frame (generated by an external simulation program). When I just t...

I am assuming this is a Mac problem because my gui worked properly under linux. I have a text field as part of my gui (file opening to be exact) and I cannot enter values into it. When it is selected and I try to type in it it just types in the terminal instead and hence I cannot open the file I nee...

I finally got my code to compile on Mac OSX but now when I run the program (which I should inform you previously ran under linux perfectly) the program quits before the irrlicht window ever opens and I am left with the following error.
