Isn't that just mimicking a fisheye lens? Turn the camera's FOV up high (or focal length down low, depending on your lens unit)

That'd be easy, this is fucking with perspective in a pretty manual way.
Like, setting specific viewpoints and controlling how they transition into eachother (not moving into each viewpoint, but more like a timewarp distortion)

The only 3D software I know of that is capable of doing "manual" perspective like that is DesignDoll, but it's just a mannequin posing program.

Well, maybe there is something, but I haven't heard about it and nothing comes up on the first page with a quick search, but maybe I use wrong keywords.

There's a panoramic option for your camera in blender. I have no idea how it works but I'm assuming that it makes use of the animation timeline. Set your key frame at the origin and go sideways upward

Yeah, it pisses me off too; linear perspective is boring as fuck. The best you can do is either reproject your render or intentionally distort the geometry.

What about other programs that can load an OBJ
Can they do what I'm looking for?

Couldn't you just bring it into photoshop and use a fisheye effect? There is a nice fisheye effect in after effects that can twist and do cool things like OP's pic, so I imagine it's the same in PS. I don't use PS as much as I do AE so I'm just guessing here.

I am not sure. Any rendering program that lets you import textures can be used for reprojection since all you're doing there is defining a wonky uv map for your original render and rendering again. You can also use Photoshop or similar as >>852437 suggests for equivalent manipulations.

>>852437
For me at least, anything equivalent to reprojection is not enough. This is because visibility in the scene betrays the linear nature of the render; consider how we can see both sides of slim objects when they are close to our face. No reprojection technique can take a render of a cube showing three sides and make it reveal the four (or more) we can naturally see. For less abstract examples, the fags at FOVOtec (or w/e) have some nice renders that take things like this into account. Basically, I want to make my renders look like shitty drawings with broken perspective, because said shitty drawings have 1000x more soul than what amounts to a virtual photograph that doesn't even match the way we see the world.

Now, what do you mean when you say "reproject" your render?

Anonymous at Thu, 23 Sep 2021 08:48:30 UTC No. 852528

Thats like a cropped cubemap or spherical projection thats been rotated. If you render out a 360 degree hdri map with a rotated camera you will see the same thing.

I can tell that image was made in the source engine. They exported a cube map, converted to lat long projection, then used some software to rotate the sphere so the horizon line is no longer a flat line along the middle. Most software and processes aim to prevent this.

Nah, it's a bunch of screenshots auto-stitched together in Photoshop.
It "works", but I'm not 100% sure how to control it how I want to.

Anonymous at Thu, 23 Sep 2021 10:26:27 UTC No. 852554

>>852536
Youll get control if you render out a sphere and adjust its projection. If you want to start coding, make your own custom camera matrix. Pic related.

The screenshot stitch method is a lossy imitation, its straight forwars if youre sitting on top of realtime rendering. You could batch render a series of photos with a camers turn but at that point why not just do an 8k sphere? Your photo series will have tons of redundant rendering.

In cycles go to camera settings change the camera type from perspective to panoramic. Then there are a bunch of fish eyes lenses that you can change the focal length of to maybe get what you are looking for.

pretty sure that's just a regular equirectangular panorma, rendered with with a resolution resulting in a fov of about about 190° and 100°
It's tilted (roll), pushing the left side up and the opposing one (right) down.

There is no real "crazy" perspective going on, unlike the in >>852078

Can blender use geometry to project camera rays? If so then it's easy.

Bump for interest.
