Problem running tests #11

Closed cartuchogl closed 10 years ago

cartuchogl commented 10 years ago

Hello,

I clone the lastest version and I try to run test/glversion.js with that result

$ node test/glversion.js 

/Users/cartucho/Repositories/webgl/node-webgl/lib/platform_glfw.js:75
            GLFW.OpenWindowHint(GLFW.WINDOW_NO_RESIZE, 0);
                 ^

    at Object.platform.createWindow (/Users/cartucho/Repositories/webgl/node-webgl/lib/platform_glfw.js:75:18)

    at Object.<anonymous> (/Users/cartucho/Repositories/webgl/node-webgl/test/glversion.js:5:23)
    at Module._compile (module.js:456:26)

    at Function.Module.runMain (module.js:497:10)
    at startup (node.js:119:16)
    at node.js:906:3

I try to change the call to OpenWindowHint to WindowHint and then fail with

/Users/cartucho/Repositories/webgl/node-webgl/lib/platform_glfw.js:83
            if (!GLFW.OpenWindow(width, height,
                      ^

    at Object.platform.createWindow (/Users/cartucho/Repositories/webgl/node-webgl/lib/platform_glfw.js:83:23)
    at Object.platform.createElement (/Users/cartucho/Repositories/webgl/node-webgl/lib/platform_glfw.js:55:22)
....

After Modify OpenWindow call to CreateWindow and minor dirty changes like:

var kk = GLFW.CreateWindow(width, height, "test");

// make sure GLEW is initialized
WebGL.Init();

//GLFW.SwapBuffers();
GLFW.SwapInterval(0); // Disable VSync (we want to get as high FPS as possible!)

for (var l = 0, ln = resizeListeners.length; l < ln; ++l)
    GLFW.events.addListener('resize', resizeListeners[l]);

var size = GLFW.GetWindowSize(kk);

And now this test runs... But when try another tests like lesson02.js, it open a 800x800 black window that only can force close to exit.

This tests are over a MacOSX 10.8.5 with a NVIDIA GeForce GTX 660M

Any idea?

Thanks for your support.

I'm experimenting the same bug.

cartuchogl commented 10 years ago

I made a little change to node-glfw to compile using system libraries. Then I update code in node-webgl to use modified feature/nan_glfw3 branch of node-glfw and updated to glfw3 new style.

Now test/lesson02.js, 05 and 07 runs nice.

Thanks it seems to work. Though there is some issue with retina: screen shot 2014-06-15 at 10 01 49

but it is maybe unrelated to your changes right?

cartuchogl commented 10 years ago

May be related with http://www.glfw.org/faq.html#why-is-my-output-in-the-lower-left-corner-of-the-window I update with https://github.com/cartuchogl/node-webgl/commit/727e3fa0f9cac9b63c9a638a2bfa4716e5a68b06 Can you test if that fix your problem?

gre commented 10 years ago

It's fixed :-) Thanks

cartuchogl commented 10 years ago

I tried with lastest master code and runs nice.

mikeseven commented 10 years ago

I'm glad the new release works well. I tested it on Mac 10.9.2 and windows 7/8.1.

Hi mike,

Getting are nonworking tests under linux (Linux Mint 16 - Ubuntu 13.10 64bit - Intel HD3000). All I get is a 800x800 black window that only can closed with a force quit on cube, lesson02, lesson05, lesson08. The window title is 'undefined'.

Tried the npm package, and master branch. Same issue. glversion.js works fine. glfw (3.0.4) tests works fine. glew (1.10.0) tests works fine. node-glfw tests works fine as well.

Really struggling with this one, and not sure how to proceed from here. Any help would be appreciated.

mikeseven commented 10 years ago

Just to be sure about your configuration. You installed the latest versions of glew, glfw3 and built AntTweakBar? Did u test examples coming with glfw3? If all this works, then let's test the example in node-glfw. You should see a triangle. And the other one should show AntTweakBar menu window.

If node-glfw works, then node-webgl should work as well.

Let me know.

Hi mike,

The versions I have (and compiled) are; AntTweakBar 1.16, GLFW 3.0.4, GLEW 1.10.0.

GLFW3 tests works, ie output from glfwinfo (all the other ones works too, windows, titles, etc)

 etc etc etc

Both tests for node-glfw works fine. Spinning triangle in both, with atb working fine in its test. glversion.js works fine in node-webgl/test/

Putting in some simple logging into lesson02 seems to suggest that the app halts on the second time through drawScene in the gl.clear statement. The result being a solid black window with 'undefined' in its title requiring a force quit to kill the app. No other messages. Not sure how to debug this further?

hschougaard commented 10 years ago

Maybe it'll help, maybe not... I replaced the requestAnimationFrame with a setTimeout. Nothing gets drawn. Title is 'undefined'. Changing the clear colour to red, still gives a black screen.

mikeseven commented 10 years ago

Your setup is good. I don't see any reason it wouldn't work.

I'll test on a Linux machine tomorrow.

everything I have ran in node-webgl is working OK on my ubuntu 14.04 64bit

stens@kamchatka ~/bin/nodejs/lib/node_modules/node-webgl/test $ node glversion.js Status: Using GLEW 1.10.0 OpenGL vendor : NVIDIA Corporation version : 4.4.0 NVIDIA 331.89 shading language version : 4.40 NVIDIA via Cg compiler renderer : GeForce GT 645M/PCIe/SSE2 extensions : 292 ...

As a preliminary step to get node-webgl working I installed glfw from source. Here is its test

glfwinfo GLFW header version: 3.1.0 GLFW library version: 3.1.0 GLFW library version string: "3.1.0 X11 GLX glXGetProcAddress clock_gettime /dev/js shared" OpenGL context version string: "4.4.0 NVIDIA 331.89" OpenGL context version parsed by GLFW: 4.4.0 OpenGL context flags (0x00000000): OpenGL context flags parsed by GLFW: robustness OpenGL profile mask (0x00000000): unknown OpenGL profile mask parsed by GLFW: compat OpenGL robustness strategy (0x00008261): none OpenGL robustness strategy parsed by GLFW: none OpenGL context renderer string: "GeForce GT 645M/PCIe/SSE2" OpenGL context vendor string: "NVIDIA Corporation" OpenGL context shading language version: "4.40 NVIDIA via Cg compiler"

That bottom line in above regarding shading language version is very important. Code will fail if you attempt to run a shader which demands a higher version than your OpenGL context provides.

@hschougaard I see your driver implements shading version up to 1.30
which is fine for rendering lines and such but will fall over when attempting to run webgl using a shader demanding a newer driver. Assure you are using the newest graphics card driver your hardware can handle. Also take note - if you are on a laptop often they have more than one GPU card - one for everyday light use and another for intensive use. On linux issue this to list your hardware video card(s)

lspci -nnk | grep -iA2 vga

here is what my laptop says ( NOTICE I have Intel for light use BUT an Nvidia GPU as well)
