Doesn't have color after calibration

[djsmartboy]

Hello,

I having some trouble with the software after i have calibrate the kinect and the beamer i start the game the welcome screen will appear nicely in color but after that i don't have any color or image on the sandbox

[djsmartboy]

Anybody?

[zzzeddy]

I have exactly same problem. I need help!

Platform

• Windows 7, 10
• Kinect for Windows v1 (with recommended usb driver at tutorial)
• Magic-Sand S/W (latest)

Symptom

• Calibration is successfully done but no image on sand
• pressing spacebar , game starts with welcome image but not with contour images

[KondakovArtem]

Hi, I seem to have the same problem. And there is a suspicion that the problem is in the shaders. Calibration is successful, the game starts, fish appear, but there is no height map.

At the same time, shader compilation errors appear in the application console I tried replacing shadersGL2 with shadersGL3, errors disappeared, but the height map did not appear

Please tell me, maybe there are ideas what could be the problem

After 2 weeks of research, I solved the problem by installing a clean Window 7 + Visual C ++ run-time components distribution. Apparently some later versions of VC run time or something else that resulted in an error were installed.

I also managed to build an application for Linux Ubuntu, but only on version 14.04, because it uses gcc 4 version, which is suitable for openframeworks 0.9.3

[kreosz]

Hi. What versions of Visual C ++ do you have installed on Windows 7? I am struggling with the same problem.

[KondakovArtem]

Hi Now i have this installed I think 2015-2019 is enouth, but it is not exactly

[RasmusRPaulsen]

It seems that the graphics card or the graphic drivers does not support OpenGL Shading Language version 1.4 (#version 140) which is required to compile the shaders used for the height map.

I found a tool that can show the OpenGL and shading language version of your hardware here: https://www.realtech-vr.com/home/glview

I hope this explains that weird looking error. Best, Rasmus

[KondakovArtem]

I also managed to build and compile the application for Linux Mint 19 and openframework 10. Apparently, they changed the work with kinect v1 in openframework 10. Everything works, but from time to time (every couple of seconds) the height map image is covered with noise, and it breaks the height lines. So I had to compile on ubuntu mate 14.04

[kreosz]

Thanks for the answers. The only option on these graphics cards. I tested on three computers, three graphics cards (but old, more then 7 year), two systems 7 and 10. I installed Direct, openGL, all Visual C ++, etc. Still the same problems 0(29) : error C7532: global type sampler2DRect requires "#version 140" or later 0(29) : error C0000: ... or #extension GL_ARB_texture_rectangle : enable 0(46) : error C7531: global function texture2DRect requires "#extension GL_ARB_t exture_rectangle : enable" before use

when i try shadersGL3... i have dark screen, but I can turn on the fish and rabbits.

[KondakovArtem]

What I did. I took a clean disk, installed Windows 7 64 bit, installed ms visual studio 2015, and what comes with it out of the box. The program worked for me on geforce 660 gtx, geforce 7200 gt (slow), rtx 2080, on AMD I did not try, because It was not at hand

[RasmusRPaulsen]

Okay. It seems that this problem is related to the capabilities of the graphic card and also what version of the graphic card drivers you are using. If you have an older graphic card, try to install the latest drivers for it. If that is not helping, then a newer graphic card is probably the solution.

Technically, the shaders uses an OpenGL extension (GL_ARB_texture_rectangle) that requires a certain version of OpenGL to work. I found this list with known graphic cards that support that extension:

https://feedback.wildfiregames.com/report/opengl/feature/GL_ARB_texture_rectangle

[kreosz]

Thank you very much for help. I bought a used GeForce GTX 660 graphics card (MSI N660 TF 2GD5 / OC). After uploading the latest drivers. It started. The children are happy!

[marcelrv]

I'm struggling with the same. Grey screen. However, the grapics card is reports GL_ARB_texture_rectangle. Is there a way to find which other ones are requested?
