How to set askew frustum camera matrix?

Hi folks,

How it is possible to set the camera projection matrix to an oblique / custom frustum?
In the mat4-module is the helper function for constructing a frustum matrix, but I can not find a way to apply it to the camera projection matrix.

I would like to have control over the image render borders - a function like

m_camera.set_frustum_planes(camobj, planes)

would be much appreciated.
In the camera module exists already a method for obtaining the camera frustum planes, but not for setting them.

Or, for now which other possibilities exist?
Please help with some hints,

Daniel

Hello!
Unfortunately, for now there is no API method to change camera frustum planes.
Could you please specify a little bit your task?
Maybe set_fow or translate_view methods from the camera API module can be useful for you

With a custom camera frustum it would be possible for us to generate e.g. very high-res images by tiling the original camera-frustum into a grid and render each tile separately.

, beside other usages like 'image-cropping' for exact control over the final image and its resolution.

As far as I can see set_fov method may help, but you should make sure that canvas aspect ratio is equal to a tile's aspect ratio

Thank you Konstantin, for trying to help.

Hi Konstantin,

as you have mentioned in Post #10028:

and in Post #10049:

there is, unfortunately, no way "tile-based high-resolution-image-rendering" and "advanced image-cropping with control over resolution" will be possible with the Blend4Web-Engine.

Setting camera fov (and or camera-position) won't get the right perspective for a tile in a way that they could get assembled to a whole without perspective kinks in the resulting image.

We have to search for another solution, then.

Cheers, Daniel.

Hi Daniel, I've just sent you a message on this topic, please check your email.

Hi Konstantin , I hope you are fine. I am looking a devoloper for my project. The project about jewelery configrator. I already created my models.
