Hi Duncan,

during production in Zoomview Builder, I don't need to rotate the image.
At runtime, If you mean showing a zoompoint image inside my navigator, I can now zoom it In/Out or show a part of the image. But for plan of commune (land of registry) for example, some of labels are vertical . So users need to see the plan with a 90° rotation when most of labels are vertical. Is it possible with a simple mouse click (or something like that ?).
(The image can only be converted one time without rotation because of disk spaces (a lot of GigaBytes).

I don't really understand your solution with special effect. How to put the Zoomview on a plane ? I've never used camera until now. What does UV means ? Do you have an example or can you give more details ?

TIA,

David

Hi DavLeMag,

The solution is rather complex, If you are new to our xml language, it would be very difficult for you to create without an example. I'll try to find some time tonight to put one together. Basically there are the following steps:

1) place a plane that fills the VMP window outside the camera (so it doesn't move)
2) use the ZoomView image as a texture mapped to the plane.
3) customize the interactions (zoomin, zoomout, etc) so that they map the textureCoords to the UV coords.
4) create an animation for rotation... you could either rotate the plane or modify the UV coordinates.

UV coordinates are basically the x, y mapping of the image on the surface of an object. By modifying the UV coordinates you can specify the translation and rotation of the image on the surface.

ok...

Thank you very much !!!
We now have everything ou customer needs !!!!

Great support...

Hi,
Without 2D rotation, the image is a very good quality, good colors, etc...
When I use 2D rotation in my mtx file, the image become fuzzy, too clear, and bad qualiy.
How can I proceed to correct this problem ?

For exemple, I've already seen if I put 512 instead of 256, the fuzzy image become a sharp image.

<MTSMaterial ID="0">
<MTSTextureMap Type="Diffuse" Name="image1" x="256" y="256"/>
</MTSMaterial>

But how can I find again true colors and brightness ?

Thanks.

Hi Tribe,
I don't have a good idea of your situation. Can you explain further? What and when are you rotating?

Hi,

I've found one solution.
In mtx file, I tried to change the values of parameter "RenderMode" and the colors and brightness became good.

About fuzzy image, I put a bigger value for the parameters x and y into "MTSTextureMap" section and I added the parameter "ZoomMax=3" into the "MTSTimeElem" section. So, the image became a sharp good quality image with true colors, moreover we can zoom on it without problem.
It's perfect.
Thanks.
