Week 2 - Computer Aided Design
this week we are going to explore different computer aided design.
Assignment
- do model (raster, vector, 2D, 3D, render, animate, simulate, ...) a possible final proejct
- try compress your images and videos
- post a description with your design files on your class page
2D modelling
To model in 2D you can use a raster and vector based program, which makes use of the concept of a rectangular field of pixels and you basically define the color and transparency of each pixel.
Rastor
I am taking a look into how raster work.I installed GIMP
Imported a picture and used lasso tool for selection
carefully selected each part of the subject.
cut out the subject from the background
uploaded another image and pasted the cut out part in it.
Vector
I used Inkspace to vectorise a blurry malayalam text from a screenshot which means "Just Do It" in english which i was longing for long time to recreate. the problem is that i was not able to find out this font on internet.
i cropped the text part and used bit mapping tool to extract the text.
i got an average result even though image was very pixelated.
3D Modelling
i have previous experience with fusion which i used for 3d printing some designs.once i traced an image of a phone holder from internet to 3d print in from tinkerspace
onshape
onshape is something that have not used before. but i the idea of an cloud based product development platform which allows live collaboration.
i tried this platform to make a simple 3d design
Fusion 360
i am building a clean render of my final project using fusion meanawhile to get knack of this tool when build a bulb to get used of this tool
i created component for each part of the bulb ,given proper dimesion with constraints .extruded this using revolve tool.added material for each part .finally added this in render page ,setted the environment and rendered it in cloud to get the below result.
FINAL PROJECT RENDER
HERE IS MY DESIGN FILE .THIS IS A FIRST DRAFT OF MY FINAL PROJECT.
Video Encoding
I downloaded the ffmpeg and manipulated its size and compressed the files using cmd line tools.
Auto Image conversion
Since i am using obsidian for documenting . i found out this community plugin to auto compress images when copied to the notes.
Conclusion
Week 2 was an immersive exploration of CAD techniques and tools. From raster and vector modeling in 2D to advanced 3D modeling in Onshape and Fusion 360, I gained valuable insights into the design process. The experience with video encoding and image conversion further enhanced my understanding of multimedia manipulation. Overall, it was a productive week, and I'm excited to continue refining my final project design in the coming weeks.
