Hey all,

As per sir's instructions, i am posting the presentation slides. I have increased the size of the pictures and have reduced the text size..

Slide 1

This slide basically, lists the stuff we have done till now. It lists the points in brief!!!

Slide 2

We started with the following experiments. We started with a wikibook tutorial and made the figures above. Though it was a stepping stone, it was what got us started..

Slide 3

After the creations which really did not have anything to do with our project, sir asked to start modeling apparatus
which is what is really required for the project. The above was what we tried for making glass and making some fluid inside the glass.

Slide 4

This was the first breakthrough we acheived in texturing glass. We learned about hemi lighting. We also put the light inside the beaker, so that we get internal refraction..

Slide 5

Since water is one of the main parts of the experiment, we tried to make the dynamics of the fluid. We learnt about baking the fluid as well as about the domain. The blender automatically calculates the physics of the fluid..

Slide 6

We started modeling pipes and the problem we faced was that we could not close one end of the pipe. We later realized when Gokul put it up on the blog that we could use curves to them simpler.

Slide 7

The picture on the right is the picture of the actual experiment. The screenshot on the left is that of the .blend file of the same experiment. We tried making the outer flask. Simply by using extrude and scaling...

Slide 8

As we were getting stuck up, sir advised us to continue with the modeling of the other parts if the experiment. Hence we started with the tap...

Slide 9

Sir suggested that we try sketching so that we can get a proper proportion while doing the apparatus as proportion is the key here. Bhairav did the sketch but was not able to remove the creases that had got formed. By the use of CNTR+N, the normals got recalculated and the creasing went. I have pointed out the edges..

Slide 10

In conjuction to the above post, we also edited the joints and we made a hole in the tap which was not made earlier int the sketch..

Slide 11

This is the position we are currently in. We have reavhed here and have started modeling of the apparatus and paln to finish it as soon as possible.

Will keep posting as progress happens,

The Plan Of Action as per my latest conversation with Sameer Sir:

1. Presentation : Preparation of a presentation (ppt) outlining our journey with blender. This includes everything from our R&D, the tutorials that we followed and things that we have created with blender. This also needs to outline what each of us has contributed individually.

2. Modelling : Regarding the actual modelling of the 1st experiment, the plan remains as it is. We're sipposed to midel the individual sections of the expt. as decided. Bhairav's sketch remains as it is, and we start from scratch. I am supposed to speak to Bhairav about this, and I haven't done that as of yet, but in all probability we start from scratch.

We're going to IIT on Wednesday, 27/08/08 to update Sir on our progress.


P.S. Wrt to Nitin's post about the face filling, it is a SERIOUS pain. Shift+F creates additional edges differently before filling the face, distorting the smoothness of the overall surface. Someone pls find a solution, it is really frustrating.

While editing...

while editing some pipes in model made by bhairav unknowingly i deleted one little surface but after doing some editing in the model i resaved that file than i looked once i found that i deleted one surface so now i have to make it again for that i tried shift+F method but i didnt get the surface way i wanted than i did it with exrude and grab method than coinciding each vertex and than remove by pressing W and REMOVE DOUBLES method but it is very much time consuming so people if u find some other and better way than please let me know...

and to make anything spherical or a set of vertices forming a loop into circle shape there is tool called TO SPHERE is available for that we need to select the loop of vertices after that make the CURSOR->SELECTION by doing this 3d cursor will come at the center of the selected loop of vertices and after that press TO SPHERE tool in MESH will form a circular shape and the 3d cursor will act as a center for that circle..


To Remove Unwanted Edges

on first look it appears there is some edge is there than after we thought its because of some bug in blender...than we left this problem but its not a bug in blender its actually something else which even i dont know but we can remove it by increasing subsurf level or there is another method which i got from video tutorial thanks karan for for that select the object in edit mode than press Ctrl+N and than say OK for RECALCULATE NORMAL OUTSIDE after doing this those unwanted edges will disappear take a look at this pictures now

The functionalities of textures.

I had started developing the model of the thermostat as shown in the figure for the first exp we guys are working on. Now if you look at the picture u can see the small vents on the cylindrical body. now to copy this effect I painstakingly deleted faces from my model creating something as shown in the picture. It took me quite some time and effort manually deleting those faces. Then when Sameer Sir came down to take a look at what we had done all day i proudly showed him my work! But sir was quick to point out that deleting the faces was a waste of time n that the same effect could be given to the object by just applying a texture to it later on.

Thus the moral of the story and the point of this post-whenever you are designing objects which have holes or vents as in this case but you need not know what exactly is inside the hole, you need not actually make the holes but just adding a apt texture to it will suffice and bring about the required effect saving time as well as effort!

Bhairav's Sketch Edited

Alright..cheers to Bhairav for the amazing sketch of the apparatus..When Nitin got the .blend file over to my place we realized some of the pipes were flat and others were's the final product after we ironed out, or rather spherical-ized the pipes..

Few mistakes still need to be fixed though..
-Nitin and Chirag.

Next Assignment

The next assignment we have is to learn and understand the importing of jpegs into blender so that it can be traced. It needs to be done so that the while making beakers and others apparatus, the proportion is proper. Anyone who works on this, should upload the results.

Making glass Pipes In 5 minutes

i came across this technique by chance , i was playing around with the bazier curve and suddenly i saw the option of bavel...well it basically spins the curve across the baveld object. So i spun a bazier curve along a bazier circle and Voila ! i got a pipe. By applying the material effects for glass in 2 minutes i had made a glass pipe. By using the Extrude option i could change the size and shape of the pipe. i am posting the image of the rendered file. I shall post the .blend file on yahoo groups once i make a better one.

here is the image

We tried making a pipe, but were not able to make the surface to join the two concentric sides.. Anyone has any tips??

Water Material Specs.

Its a relief Gokul and Karan have cracked the (rather non-existent) problem with the tank and water creation..So, great work guys..
Here's the material specifications for water:

RayMirr: 0.56
Fresnel: 0.8
FAC: 2.62

IOR: 1.21
Fresnel: 0 <---- Very important if you want a coloured liquid.
FAC: 2.62

Ref: 1
(CookTor)Spec: 2
Hard: 32
Tralu: 0.34
Enable TraShad as well.

For the colours I used a dark one for the Col value
A lighter one for the Spe value
And true white for the Mir one.

Set the Alpha value at 0.355
