This week I followed a tutorial that demonstrated how to model a lamp using nurb curves and cylinders. The tutorial wasn’t too long but for some reason it didn’t show how to model a light bulb for the lamp.The shape of my lamp base didn’t end up looking similar to the one made in the tutorial because I’m not that good at drawing curves but it didn’t end up looking bad. I learned that for corners if you place around 3 CVs in the same spot that it will make the corner more sharp. Also I learned that when you revolve a CV curve if the curve is turn in a little then the shape will actually be curve and in some. Below are some pictures of progress and final renders with plain color.
This week I followed a tutorial that showed how to model a TV using various tools and techniques. The tutorial had numerous steps and I learned a number of things from it. From the tutorial I learned:
- about using hull mode
- how to using and insert isoparms
- CV shaping techniques
Adding an isoparm isn’t really that hard. All you have to do is click and drag on an edge for where you want it, then go to Edit NURBS -> Insert Isoparms. Isoparms help with shaping nurbs objects. Hull mode is useful in shaping nurbs objects. It is also useful to use after inserting isoparms since the isoparms create hulls for helping with shaping. There are a couple of CV shaping techniques that I didn’t know before. Like for example, scaling CVs affects the shape of the nurb object.
My TV didn’t end up looking the same as the one in the tutorial because I messed up some how on the font of it, and I’m not sure how. Plus the stand part isn’t too good because I didn’t make the curve that well. I think it turned out look good for being my first “actual” nurb object that I created. Below are some pictures of my progress and a final render.
This week I followed a couple of tutorials that explained the nurbs surfaces loft and the birail tool. The loft tool allows you to select two curves and lets you create a a face between the curves in the shape of the curves. Editing the shape of the EPs/CVs changes the shape of the lofted face. I knew a little bit about nurbs surfaces loft from from previous tutorials but from the one I just watched I learned more useful tips about the tool that I did not already now. In the other tutorial I watched it showed how to use the birail tool. With the birail tool 1 (depending on which birail you choose depends on how many curves you have to select) you select a profile curve and two rail curve and it create a face there. I find the birail tool can be useful but you have to make sure that all the points of your curves and snapped together or the birail too won’t work. The first picture is of the nurbs surfaces loft and the second ones are two different views of the birail.
This week I followed a couple of tutorials that showed more basic stuff about modeling in Nurbs. I learned about about that extruding a nurbs circle and curve will create a tube like object. I also learned about the different ways to make the extrusion follow on the curve. In one of the tutorials it showed a really fast and easy way to created a egg shape using a sphere. Also I found out that nurb shapes are already in smooth preview and if you press 1 then it will be unsmoothed. The pictures below show the shapes rendered out and in Maya. (the egg was more than one color, I just don’t kn ow what happened to it when it got rendered.)
