∙ 14y agoQuite simply, it doesn't fulfill the requirements for a "platonic solid", which include the requirement that all bounding areas must be regular polygons. A square is a regular polygon; a rectangle is not.
Gouraud Shading is effective for shading surfaces which reflect light diffusely. Specular reflections can be modelled using Gouraud Shading, but the shape of the specluar highlight produced is dependent on the relative positions of the underlying polygons. The advantage of Gouraud shading is that it is computationally the less expensive of the two model, only requring the evaluation of the intensity equation at the polygon vertices, and then bilinear interpolation of these values for each pixels. Phong Shading produces highlights which are much less dependent on the underlying polygons. However, more calculation are required, involving the interpolation of the surface normal and the evaluation of the intensity function for each pixel.
Polygon Method Of Adding Vector1. Draw the first vector using a scale.2. Connect the tail, the 2nd vector to the arrow head to first vector. Repeat desame procedures with the other vector.3. Join the tail of the first vector to the arrow head of the last vector to determine the magnitude and direction of resultant.4. The length of resultant draw the scale determines the magnitude and the direction is the angle between the arrow head of the last vector.
CONVEX- Having a surface or boundary that curves or bulges outward, as the exterior of a sphere. - curving outwards like the outside surface of a ball [Latin convexus vaulted, rounded - Curving outward, like the outer boundary of a circle or sphere.
First condition for equilibrium. Insofar as linear motion is concerned, a body is in equilibrium if there is no resultant force acting upon it, that is if the vector sum of all the forces is zero. This condition is satisfied if the vector polygon representing all the external forces acting on the body is a closed figure.Equilibrant of a Set of Forces: This is defined as that single force that must be applied to keep a body in equilibrium when it is under the action of other forces. This equilibrant (sometimes called anti-resultant) must be equal in magnitude and opposite in direction to the resultant of the applied forces.http://blog.cencophysics.com/2009/08/composition-resolution-concurrent-forces-vector-methods/
1260 degrees
Hint: in a regular polygon interior plus exterior = 180o, always.
The sum of the exterior angles in any polygon is 360 degrees.Therefore that polygon is a decagon.
1440 degrees
1440 degrees
Each interior angle of the regular 5 sided polygon measures 108 degrees
360
If the exterior angle is 30o then the shape has 360/30 = 12 sides. An interior angle = 180 - exterior angle = 180 - 30 = 150. Since the shape has 12 sides the interior angles sum to 150 x 12 = 1800o.
The sum of a regular polygons exterior angles always = 360
Providing that it's a regular polygon then its interior angles will add up to 1260 degrees with each of its 9 interior angles measuring 140 degrees.
