Week 3
2D designing in photo shop and 3D designing in rhino
I got introduced into 2D and 3D designing in the third week.
I installed photoshop and started editing on it.I really liked the interface.
I installed rhino and the interface was very different.
I designed some basic components in rhino.
I am planning to make a 3D design of a drone
Neil also gave us an idea about raster and vector files.
I edited a photo of my own In photo shop.I learned how to make layers.
In rhino I designed a drone. I learned how to extrude.
DIFFERENCE BETWEEN RASTER AND VECTOR IMAGE
Raster image is made up of individual pixels. Each pixel contains only one colour and is arranged in a certain fashion to make up the image. This is how normal pictures are displayed. The problem with raster image is that the maximum resolution is limited by the number of pixels. That means, when you try and scale the image into a larger size, the quality drops and the edges of lines become fuzzy (staircase effect). This is the major limitation of using raster images.Raster or bitmap files are pixel based and when we zoom in raster files we can see pixels and each pixel are given specific color. So, raster files are only scale able downwards and they are mainly used to make raster graphics. At the same time, vector files are scaleable and each curve is made using mathematical equations. Different type of vector files is pdf, cps, svg etc. I installed photoshop and started editing it. I really liked the interface and there were many tutorials available. I went through some of them and our instructor gave us some tips on shortcuts and using the pen tool.
vector image is composed of paths, which are represented by mathematical functions. These mathematical function represents the actual borders and the different elements in the image. Hence the maximum resolution of the image is not limited by the number of pixels. These mathematical functions can scale easily giving lossless ability to zoom to any extent on the image.
You can erase pixels in a raster image using the eraser tool but, that is not possible in a vector image. In a vector image you can only trim the path according to some constrains.(I got this great explanation from the internet)
2d design softwares
3d design softwares
the 2d design
phtoshop
Photoshop is a raster graphics editor developed and published by Adobe Systems. It's a Proprietary software .
In Photoshop all things is based on the Layers, here in my design you can see Layers in the left side , each component have it's layer , it's make our works easy . it's like a object in programme, and we can call it any other design and modify that.
GIMP and Photoshop are for same purpose but main differnce is that GIMP is under free and Opensource but Phtoshop is Proprietary. and Krita is one of the awsome tool for Drawing and Render Animation. for simple rough drawing MyPaint is great.
I used Wacom graphic tablet with photo and it worked perfectly and fine.It is a great tool to draw in natural way.S
the 3d design
Rihnoceros is a computer graphics and computer-aided design application software.I don't have any experinece in 3d design.so i just started with rihno , i first tried to make a 3d model of a drone.
SO firts draw the 2D Image , In Rhino we can simply switch between views ,and better to draw 3d in Top view . we can use left corner dropdown.
how to draw lines and curves
then I drew my design
I used Extrude Crv tool to extrude the curves in Presepectice View.I extruded the whole 3d in to height of the actuall part.actually in Extruding Crve we are converting 2D in to 3D.
