Season's Greets from FBSL!

[Mike Lobanovsky]

This project is fairly large for an application written entirely in BASIC (~3.8K lines of predominantly OOP code) so I decided to narrow down my submission to an executable only.

I also apologize to those who won't be able to run this GLSL program on their machines. Christmas time would probably be the best time to pamper oneself with a nice little present, a budget discrete graphics accelerator card from nVidia or ATi.

Merry Christmas, guys!

[jj2007]

Do I need a new version of FBSL, or just a new graphics card?
Merry Christmas, Mike ;-)

Merry Christmas, Jochen!

These messages from the GLSL compiler signify that your OpenGL support is very, very basic.

You may try to download and install the latest GPU driver available for your particular chip from your vendor (presumably Intel?) but I am not sure if that's gonna actually help. nVidia is Number One in the industry with ATi following closely behind as Number Two while all the rest are unfortunately numbers zero. Their graphics acceleration is barely sufficient to cater for Windows Aero only.

A discrete graphics card from nVidia or ATi would be the best solution. Both of them offer a wide range of desktop PC graphics accelerators in the first place but laptop solutions are also available.

You don't need any upgrades for the executable proper. It is compiled with the latest FBSL v3.5 though the script itself was written in the times of, and was fully functional under, FBSL v3.4.10.

[jj2007]

nVidia is Number One in the industry with ATi

NVIDIA GeForce 610M on an Intel Core i5.

[Mike Lobanovsky]

So what Jochen? Do you mean that's what you have and that's what refuses to swallow my code?

If so then goto nVidia, make sure you have the latest Java installed and click Auto-Detect Your GPU. It will examine what's really there in your laptop and if satisfied with the findings, it will suggest the best and newest driver it has in stock for your configuration. Don't put on airs and let it download and install the driver for you. You'll be amazed with the results when done.

And after all, if for some reason you aren't satisfied with the results you get, which is highly unlikely tho, you can always roll back to what you had before like you normally can with any new driver you're installing.

See below. The driver comes from here:

Code: [Select]

Version 376.33 - WHQL
Release Date Wed Dec 14, 2016
Operating System Windows 7 64-bit

[Mike Lobanovsky]

Jochen, my friend,

Probably ZXDunny's brainwash has affected you more than was really necessary: your latest teletype communication style is too cryptic and uninformative. The screenie I'm seeing beneath your post looks like a very base immediate mode OpenGL sample run through MS Windows own medieval default OpenGL v1.1 software renderer (included only for gigs because OpenGL is, and has always been, a winning competitor to their own DirectX stuff), rather than a decent GLSL application.

Do you mean to say you've got that 376.33 driver installed but still can't run my application? Have you had NVIDIA Control Center installed along with this driver? Does its nVidia icon show up in the tray notification area of your Taskbar?


[ADD] If you still can't run my Xmas Tree then will you also try the following animated Julia script which is a very, very basic (though beautiful) GLSL application? It runs for me @30 FPS w/ 0% CPU and 13% GPU full screen even on my kitchen toaster, let alone the PCs of OxygenBasic community members.

If you can't run this one either then I'm afraid you must be in some serious trouble with your Win 7 laptop, Jochen...

[jj2007]

JuliaParticles runs fine. The other one gives the same error messages with the latest NVIDIA driver. And yes, control panel and icon are there. What is GLSL, a Windows component?

[Mike Lobanovsky]

Glad to hear you can run at least basic GLSL applications.

GLSL is part of OpenGL specification that allows HW accelerated graphics operations to be executed in parallel on the multiple kernels of a modern GPU. Your particular GPU chip (more business- than game-oriented) has 40 such parallel processors while each one of my two GPUs has nearly 200 of them -- and that's a pretty low budget solution for a modern gaming PC. Evidently nVidia drivers (regardless of their version number) targeted at mobile GPU chips of the GT (M) series lack certain front end features (called "extensions") that are readily available in the (overclockable) GTX drivers like mine.

The GLSL compiler is not a regular Windows component, but rather a part of nVidia/ATi driver installation. Windows DirectX has its counterpart called HLSL. The two aren't shader source code compatible. While GLSL looks pretty much like ANSI C (see the shaders inside my zips), HLSL would look more like some weird assembly. The GLSL compiler is however capable of translating some very simple HLSL sources to GLSL compatible code.

[jj2007]

OK, I keep learning.

PrintLine "[", rv(glGetString, GL_VERSION), "]" returns [3.1.0 - Build 8.15.10.2418]

[Mike Lobanovsky]

It's good to know your config supports OpenGL 3.1. IIRC GL_EXT_gpu_shader4 (it pertains to the so called "geometry shaders" that allow 3D vertices to be generated on the fly directly on the GPU rather than manipulate only the vertices that were pre-generated in the form of a 3D model) has been promoted from "EXTensions" to the core functionality in OpenGL 3.0. I'll experiment tomorrow evening a little to see if the code can be modded to work using core OpenGL only.

It may eventually happen that you'll be able to see my Christmas Tree on your desktop in the long run.

[jj2007]

It may eventually happen that you'll be able to see my Christmas Tree on your desktop in the long run.

That would be a very special Christmas present, Mike, but don't put too much effort in this - you should be running around organising presents for kids, grandsons+daughters, little nephews etc...!

[Mike Lobanovsky]

Oh Jochen,

I can't physically be "running around" any more nor do I have any daughters or nephews, but I do have grandchildren. But I still can cheat a little: there are two official Christmases in my country, one Catholic and another one, Orthodox.

I need a little help from you. Can you please run a little script for me that's in the zip below? It will poll your OpenGL/GLSL capabilities and I hope I'll be able to adjust the shaders accordingly. Regretfully geometry shaders have been moved to core OpenGL starting with v3.2 only but the extension options may still be hidden somewhere in your driver under different names.

The script code is as follows:

Code: [Select]

#AppType Console

#DllImports OpenGL32

#Include <Include\Windows.inc>
#Include ".\COGLApp12.inc"

#Define GL_VENDOR &H1F00

#Define GL_VERSION &H1F02
#Define GL_EXTENSIONS &H1F03
#Define GL_SHADING_LANGUAGE_VERSION 0x8B8C

Dim Viewer As New COGLApp12 // OpenGL context must be available and initialized before the calls

Declare wglGetExtensionsStringARB()
Declare wglGetExtensionsStringEXT()

AddressOf wglGetExtensionsStringARB = wglGetProcAddress("wglGetExtensionsStringARB")
AddressOf wglGetExtensionsStringEXT = wglGetProcAddress("wglGetExtensionsStringEXT")

Print "Vendor:     ", ToString(glGetString(GL_VENDOR))
Print "Renderer:   ", ToString(glGetString(GL_RENDERER))

Print "GLSL:       ", ToString(glGetString(GL_SHADING_LANGUAGE_VERSION))

Delete Viewer // Destroy COGLApp12 instance with its OpenGL context

I deliberately didn't Split() the list into lines to squeeze it into a fraction of one console screenful.

I could've added conditional compilation of shaders depending on the current capabilities of any PC or laptop the app is running on but that would've been too much of a PITA on the Xmas/New Year Eve. So, I guess I'd rather re-adjust it for a typical laptop equipped with a budget nVidia card based on your feedback.

TIA

[jj2007]

Can you please run a little script for me that's in the zip below?

Which language is that? I tried fbsl but no windows.inc there...

[Mike Lobanovsky]

Hehe Jochen,

The application is in the zip below the post. You need an FBSL v3.5 installation and a COGLApp.inc file to run it from the script. Please use the precompiled app.

TIA
