I have written a java external that draw some objects in a scene. I want to set a textures for the objects.

I can create a texture object like     

texture = new JitterObject("jit.gl.texture");

but I don't know how to load the texture file or how to use that texture on a object

can you help?


loading-a-jit-gl-texture-programmatically

you might want to post in the jitter developer forum rather then the jitter user forum

texture.read(filename) will read a file. object.texture = texture.name will attach a texture to an object. I don't remember the exact syntax, but this is the gist of it.

If I am not mistaken that is how you do it if you are programming using javascript.

I wanted to do it using Java external. Any idea how to do that?

I have written simple JavaScript program to load a textures and rotate the plane after looking at several examples in the forum 

When I run it the program does work but I can see some white squares flickering all over the window and loaded texture looks different.

var mywindow = new JitterObject("jit.window","test");

var myrender = new JitterObject("jit.gl.render","test");

var mywallpaper = new JitterObject("jit.gl.texture","test");

var planepaper = new JitterObject("jit.gl.gridshape","test");

Any suggestions?

//jit window
var mywindow = new JitterObject("jit.window","test");
mywindow.depthbuffer = 1;
mywindow.doublebuffer = 1;
mywindow.size = [1000,800];
//mywindow.idlemouse = 0;
//mywindow.mode = "texture"
//mywindow.interp = 1;

//render
var myrender = new JitterObject("jit.gl.render","test");
myrender.ortho = 2; 
myrender.camera =[0, -10, 20];
myrender.lookat= [0, 0, 0];
myrender.far_clip = 1000;
myrender.erase_color = [0,0,0,1]; 

var mywallpaper = new JitterObject("jit.gl.texture","test");
mywallpaper.name = "wallpaper";
mywallpaper.read("skin2.tif");

var planepaper = new JitterObject("jit.gl.gridshape","test");
planepaper.shape = "plane";
planepaper.lighting_enable = 1;
planepaper.smooth_shading = 1;
planepaper.color = [1,1,1,1];
planepaper.position = [0,0];
planepaper.blend_enable = 1;
planepaper.texture = "wallpaper";

    ang += small_amt ;
    if (ang > 360)
        ang -= 360;

    myrender.erase(); 
    myrender.drawclients(); 
    myrender.swap(); 

please provide a simple patch that loads your javascript file and illustrates the problem.

Somehow the flickering no longer appearing now. I have no idea how it happened only thing I did was close and restart max/msp program.

However the texture still looks somewhat bluish 

Please find the attached file

I have taken a screenshot of the window. The bottom image is the actual image and the top one is how the max engendered it. It is quite bluish ...

your patch works as expected over here. if the color looks off, try lighting_enable 0.

also, please post patches using the Edit - Copy compressed option.

When I change this line I noticed that only some brightness changes 

when I changed the following line I noticed big changes in the images appearance. Still the problem is there

then I set the following line to change the lighting of the renderer still no change

is there any other settings I should try?

not sure what the problem is, but it looks like the color planes are re-mapped. the image in your screenshot is not the same as the image you posted in your zip file.

can you post the image from the screenshot as well as relevant system specs?

Yes I took the screen shot with a different image. Following is a screen shot of the image in the zip file.

As you can see it is somewhat blue colored.

Do you have a sample code that does something like this so I can have look to see what I did wrong?

I tried jpg and it looks the same.
