Text unreadable
Hello,
i'm evaluating this software because we might use it in a psychology related VR project. Now as i was watching the demo's, it seemed al text that is used to display some info in the 3d world is unreadable, if needed i'll supply a screenshot. how can i resolve this issue? greets, Kevin |
Do you know if you're running on ATI graphic hardware? Such hardware unfortuantley can cause text problems under some versions of Vizard. Which demo and which version of Vizard are you experiencing this?
If you don't know what you're graphics hardware is or if you know it's not ATI, then we would certainly appreciate it if you sent us a screenshot for further evaluation. Thanks. |
Thank you for the reply.
Indeed this system is using an Ati Rage chip 32 mb. I'm using the latest trial edition, which i download this morning. Is this glitch on all Ati chips or only on the older rage boards? By the way this happens with al examples which are included with the trial. is there a work-around? Because we might use this system to develop, but the final system which will run the VR simulation, will use a Nvidia Quadro FX 3400, that shouldn't be a problem right? I sure hope there is a workaround. Is the same function used for text to create a 2D visual interface in the VR-app with your software? thanks in advance, greets, Kevin |
First, could you please verify that you're running 2.50 or later of Vizard. Starting with those releases some texture/text handling problems on ATI hardware have been resolved. There are no known issues with nVidia hardware and we currently consider nVidia our baseline for performance.
Our ATI tests are done on Radeon hardware using the latest Catalyst drivers. Could you please verify your Catalyst drivers are the most recent, and if so, then can you try on a different ATI chipset? |

I verified the vizard version: 2.50b Next, i installed the latest drivers. note this is a dell machine and the regular ATi-website drivers did not work. But the date of the drivers of the dell website seemed to match the ati drivers published on their website (well almost, that is). This is an older Ati Rage 128 Ultra chipset. Unfortunately this card does not use the catalyst driver set. Other sys specs: P4 2.4 512mb on Windows 2000 etc. (Dell precision 340) Another problem i'm running into is complete system locks on running the 3D demo's. (ctrl-alt-delete, alt-f4, alt-tab = no response, no more mouse-movement either). This first happened with the "mini"-cardemo, and just a few minutes ago also on other demo's, this time i ran collision demo to check the font problem, and as i dragged the 3d window i got the lockup. At the moment i can not test another Ati-board @ work. I could at home though on an x800 card, but as u know i will be developing @ work, so that's no solution. I'll check if i can get a hold of another card here. Do you have any other suggestions, regarding the system lock-ups and unreadable text? (system is up-to-date as far as possible, and has anti-vir mcaffee etc) thanks in advance, greets, Kevin |
I have a intel HD graphics 4000. when I try to display text some of the letters are dim . Oddly this only happens when I update the graphics with a timer.
Has any one seen this? Thanks |
Is it screen text or world text and can you post the code you are using? If the text placed in the world and depends on the angle you are viewing from try the following:
Code:
text.disable(viz.LIGHTING) |
Depending on the TEXT used different letters will be dim .. Here they are only dim in non full screen. other times they are missing and dim on full screen.
trackDisp = viz.addText('First message on screen',parent=viz.SCREEN, ) trackDisp.message('second message from in line code') TimerID = 1 #Create a function to handle the timer events. def onTimer(num): # #Use the time ids to identify the timer. print 'timeout' trackDisp.message('this is the text from the timer 123456789') #Register the timer callback. viz.callback(viz.TIMER_EVENT,onTimer) #Start timer. viz.starttimer( TimerID, 1, viz.PERPETUAL ) |
It could be an issue with a certain version of drivers. If you haven't yet, try updating the drivers for your Intel 4000. Or roll back to an older version.
|
I just updated to the latest driver and unfortunately the problem persists
|
Do you have the same problem with text if you run the PigeonHunt demo? That uses text for a countdown timer.
|
When I change to viz.ORTHO like Pigeon Hunt it works. Does not work with parent= viz.SCREEN
trackDisp = viz.addText('First message on screen',parent=viz.ORTHO ,fontSize=20) |
