Record a high-quality image with CATIA

Hello

To create an image of my CAD, I typically use Tools --> Capture.

Then, I save my image in .png format.

On the other hand, I find that the quality of my image is very average.

Gold
1) In the Pixel tab of the capture options, the "Render Quality" choice is high.
2) In the CATIA options (Tools --> Options), in terms of the display, I put the finest precision, namely 0.01.

How can I get a high-quality CAD image with CATIA?

Thank you in advance for your advice.

Hello

Have you tried the rendering workshop? http://catiatutorial.free.fr/rendu/rendu1.html

If you're looking for a quality, make a rendering!

For high quality you must have the PHS module "Photo studio"

OK.

Thank you for your advice.

Here is my feedback on your elements:

1) In Infracstruture, I do have "Photo studio" on the other hand, I don't have "rendering". Is it the same thing?

--> actually, I think I have the answer since I just saw that I also have Real time Rendering. 

But then what is better to use "Photo studio" or ""Real time rendering"?

2) "Render" --> OK interesting why not, but could you tell me a little more about it?

 

Good evening

I don't have any of these modules but what I can say:

Photo studio is to make realistic photo renderings (very beautiful images close to reality but frozen)

Real time rendring: the rendering is recalculated when manipulating the 3D.

The success of a rendering lies in the realistic representation of the materials applied in CATIA, lighting effects (a job in itself).

By default in CATIA there are very few materials and the rendering is quite poor I don't know if with these 2 modules the choice is more extensive?

Without trying to make high quality, we have already encountered PBs with CATIA's image capture utility. In R22 and V5-6R2014 these PBs were corrected. If the image you get is of lower quality than a simple screenshot pasted in Paint, there is a chance that your release of Catia has this type of PB

"> there is a little point which I do not understand here. What do you mean by "frozen"? For me, a photo is an image at a given moment and therefore necessarily "frozen".

--> Your hypothesis seems good because I have the r21. So it could be possible. Moreover, indeed, I am not looking for a very high quality image at 20 MB but simply a decent image at 2-3 MB. However, the result obtained is still far from the correct for me. I still have big pixels that spoil the 3D effect of a CATIA part.

Hello

If you put a piece on the forum we can do a test under the same conditions and conditions.

View: Isometric.

Zoom: Center everything 

Same size of the capture window (Width x Height )

Same settings of the capture utility

Same output format (Jpeg High quality).

After that, all you have to do is compare the results.

Here's what I get. 

As soon as you zoom in a little, it's not great.

In addition, an element that can be indicative of the quality is that the image weighs 35 KB so not much. Getting a 1 MB image would have been more relevant for an image with good quality.

Otherwise, I saved my image in high quality jpeg.

I tried to set the resolution to the max by making the following setting in the snipping tool:

Thank you in advance for your help.

Hello

The capture is done in Pixel mode so the more you zoom in the more it degrades (this is a normal behavior).

The jpg is more than enough for a screenshot intended to be integrated into an "Office" document, and the size is very light.

If you choose Bitmap this will be much heavier x10 about (+ colors) but for a single color CAD image I don't really know the difference.

I have attached the results

1 - Same setting as you (jpg and bmp)

 2 - "High" setting (JPG and BMP)

3 - "high" setting ( BMP) with materials (DS red paints and two front lights).

The resolution you set to MAX is for printing.

It will seem that what I get is a bit better (in jpg 128 instead of 35) I don't think it's the capture,

 

Look at your precision settings.

Photorealistic renderings under CATIA are a real pain to set up and it lags a lot as long as you have a bit of a heavy set, when I want a beautiful image I use Keyshot.

Simple and very powerful, compatible with CATIA for updates as your work progresses.

No image format limit, I've already released a rendering like 10000/15000 pixels, a 120 MB image!

Some examples: http://www.lynkoa.com/propositions/1100-gsxr-92

Hi Mad max,

Thank you for your advice for Keyshot.

I think I should be able to produce quality CAD images with this program.

On the other hand, I have some problems with the use.

The two leads I have found so far are:
- To import my part to set the quality of triangulation to 0.001.
- In the Image tab, increase the resolution.

Then I go to render and take a screenshot.

But, for the moment, the images generated are still low (300 KB).

I would like to generate .jpeg or .png good resolution images with a size of 3-5MB.

How can I do this?

Thank you in advance for your advice
