I dabble in 3D modeling

Overview

I am an undergraduate student at BITS Pilani Hyderabad studying BE computer science. I work on small 3D projects, primarily using Blender in my free time. I love working in 3D, where I can create a world of my own, literally.

  • Ferrofluid

    Ferrofluid

     
    The physically not at all accurate ferrofluid

    Made using Blender
    Focusses on procedural displacement

    Ferrofluid is something really fascinating. It is a suspension of tiny magnetic particles in a liquid. So it reacts in presence of a magnetic field. For this animation, it is assumed that a magnet is under the table. 

    The main thing I wanted to do is to replicate the ferrofluid's attraction towards a magnet. First, I took a cylinder, scaled it down, and filled the top using grid fill for more geometry.


    I need spikes. I used a Voronoi texture with zero randomness to get the circles with fall off. Then I made an empty to control where the spikes are to be shown. So I multiplied the circles with a spherical gradient having object coordinates of the empty.


    This is plugged into a displacement node and fed to the material displacement. This only works in cycles and in displacement settings of the material, displacement should be chosen as 'displacement only' only or 'displacement and bump'. I chose displacement only. For the surface, I have a principled BSDF for a metallic look. After tweaking the textures for the required shape, this is the result.


    This is the final node setup I decided on.


    This material is completely procedural and can basically be applied to any object.


    To animate the motion of the ferrofluid, I applied an object constraint to the empty to follow the path of a bezier circle. I deformed the circle into the shape I want and added keyframes for the offset factor to have a perfect loop.


    Then I modeled a petri dish with glass material and set up a scene with a marble table with some depth of field.

    After a while, it felt lifeless and static. So I added some camera shake and made a few small modifications. This is the result.



  • The Raspberry Popsicle

    The Raspberry Popsicle



    Made using blender
    Focusses on texturing, geometry nodes, rigid body dynamics

    I guess you develop a certain eye for details once you start trying to texture anything. This is something I wanted to make after eating a raspberry popsicle. The modeling in this one is quite simple. I made sure to maintain quite a bit of geometry throughout which is something I never do. Following a few reference images, I made the ice, popsicle stick, and ceramic plate. The popsicle stick material has a tiny procedural wood texture and the ice I ended up changing a lot.



    To add more visual interest I decided to add some raspberries to the scene. For the raspberry, I subdivided a cube and made an indent at the top. Instanced the small druplets on it with geometry nodes. I decided on node setup.


    Now, for a natural position, I technically dropped the raspberries onto the plate. I made the plate and popsicle a passive rigid body and the raspberries active. When I was satisfied with the position I baked the simulation into keyframes and deleted unwanted ones. I decided to add a few under the popsicles as well.

    It still felt a bit empty so I added a few leaves. Not to waste much time on them, I downloaded an image with an alpha channel and slapped it on a plane. The main challenge for me was the ice material. I tried a bunch of different node setups. Nothing was good enough though. Finally, I figured the volume absorption node is the key. It makes perfect sense too. The denser it is, the darker it should be.

    I finished with some lighting changes and a vignette in compositing.
