With only one midpoints step, this give something like this :

You can use DevIL http://openil.sourceforge.net/, this is a relatively simple library to use

DevIL can handle a very big numbers of graphics files formats such as .jpg, .tif, .tga, .bmp, .pcx,...

Something like this http://www.opengl.org/discussion_boards/showthread.php/131788-How-to-draw-a-bezier-curve-through-its-control-points ?

Of course you can :)

Here an example that display a picture image file into an resizable OpenGL window



#include <IL/il.h>
#include <GL/glut.h>

How can I install glload and glimg libraries/headers ????

Because without them, I can't test the code with them ...

How can I install the glload and glimg library ???

Because without them, I can't test the entire code with them ...

Perhaps to make the window creation **after** the image loading ?

cf. move the bloc that initialize the GL context just after the image lmage loading instead before as now :



// make...

This version don't crash my linux box :)



#include <stdlib.h>
#include <stdio.h>
#include <memory>
// #include <glload/gl_all.h>
// #include <glload/gll.hpp>
// #include <glimg/glimg.h>

I confirm, this crash too on my linux box with a 800x600 definition :(
(I have only commented all glload/glimg lines for to can compile the code)

Have you test the values of width and height after the line 55 ?

Note that your 1600x900 window size don't seem me to be a very standard definition
(you have a 1600x1200 screen or something like...

There is a problem on the last bresenham function when the line is more vertical than horizontal :(

Here a corrected version where you can too :

- dynamically resize the window,
-...

You have forget a glutSwapBuffers() call at the end your display

And your bresenham implementation have a problem because you use int values instead floats in your division of deltay by deltax at...

With a coffee and a sugar ? :)
(note that you have forgotten the "please" or the "thank you in advance" in your request, only "I want" ...)

More seriously, you can find an example about one...

I have finally ordered a Xilinx FPGA Development Spartan-3E XC3S500E-PQG208 Board 4.3" TFT LCD 4 Nios

Where can I find one very basic/minimalistic "OpenGL (ES) like" HDL for this Spartan ?
(I...

Thanks, Tonyo_au

So I think that I have to implement something like a mixt of Forsyth's or Tipify's algos (for to handle vertices reordering) and an extended vboindexer (for to transform v/t/n[/c]...

For to manipulate the image, alls informations you need are already used at the line that load the texture from the RAM to OpenGL ...

Hi,

I begin to play a little with "advanced" things like Vertex Buffer Objects, normal/light/shadow mappings and others instancing or render to texture methods

I have founded a tutorial...

This work without the "#version 150" ?

Can you please give the code source you use ?
(for to can see if the problem is not on other part of it)

Have you test to display the string content of the ouput of your GetFile() function using printf("%s", GetFile("yourshader.txt")) ?

Because I don't see any "<" in your shader ...

And/or have...

In somes 3D model's formats, such as the .MD2 format, the vertex and matrix data are pre-processed for to minimize the size of the model's data :

I have find a link that draw an dynamic helicopter at http://www.staroceans.net/helicopter-camera.htm

I think that is more logical to add first the "simple" handling of the dynamic equation of a...

You can find DevIL tutorials at http://openil.sourceforge.net/tuts/tut_step/index.htm, http://openil.sourceforge.net/tuts/tut_5/index.htm or http://content.gpwiki.org/index.php/DevIL:Tutorials:Basics...

You can too use libTIFF http://www.libtiff.org/ , libTGA http://tgalib.sourceforge.net/ or libJPEG http://libjpeg.sourceforge.net/ but DevIL is very more generic and work really very well for...

Lots of thanks, Ilian

I think to buy the FPGA XC3S500E for to begin (your second link)

Can the devel of this FPGA to be make on a Linux box ?
(I think that yes, but in the doubt ...)

And...

DevIL is a good image loader library
