Currently working on a 2D engine, not for gaming but for design software / visualisation for machines. So far it is comming along quite fine. I started to wonder if it were possible to draw a triangle and fill it with some form of a a texture, or even better a polygon and fill that with a texture.
I know that DX can do that for me :P but I am realy focussing on GDI+ at the moment.
i'm developing a simple 3D Cad Application that renders some created objects. I'm able to apply a color-based material to the objects but not to cover their surface with a texture, such as a bitmap. These are the two main code blocks of my application:
This code, creates the objects and creates materials for them. (To draw the objects, i'm using the Mesh class' methods):
objects(0) = Mesh.Box(device, obj.SizeX, obj.SizeY, obj.SizeZ)
materials(0) = New Material
materials(0).Diffuse = obj.Material
materials(0).Specular = Color.LightGray
materials(0).SpecularSharpness = 15.0F
I created a module for the functions to create a bmp by combining 4 bitmaps together and using a bump map. This part works. It's as soon as I try to save the bitmap to a memory stream I get an error.[code]
View 1 RepliesIn the project I'm working on I've been using some gif images to define one or more texture brushes. I have the images in a folder and I know how to define the texture brushes as follows.
[Code]...
Let's say I add the images as image files to my application using "Add Existing Item". Is there a way I can define the texture brushes with the images that have been added to the solution in that way and if so could you show me the exact code.
I am creating a script editor in vb for a game engine and all is fine with the editor, I just cannot for the life of me get a mesh viewer working. If you are familiar with Unity3d Editor, it has a small 3d viewport that simple shows the mesh associated with the asset script being created where you can click drag rotate the mesh to have a look at it with the selected textures applied.
I have spent many hours digging through msdn trying to figure out how to do this. All samples I find are done in c# none in vb. I have even used code converters with no luck. Bot sure what sdk(s) to use either. How to do it as in setting up a project that has a basid 3D viewport that will also applie selected textures to the mesh? Even if it is hard coded to show a generic mesh and texture, It should be enough for me to grasp how to set it up.
I'm creating a movable scenary with, like 100 different flights. I want to create for every type of flight a triangle...so it's moves around and you have an idea how the airspace looksq like at what moment.Now my question is, what's the best way to draw these rectangles? I created a class 'Flight' and it has a Graphicspath in it. Now I want to update the triangle, which represents the aircraft, with the speed and heading...so it moves around well.

I am taking an Intro to VB class in college and for on of our assignments we need to make several shapes with *'s. The user is prompted by an input box where they decide how large to make the shapes. The only one that I am struggling with is the inverted triangle. Here is what it should look like if the user would select to have 5 rows.

View 4 Repliesi was asked to do a program which can find if a 2d point is inside a triangle or not, only the 3 points of the triangle were given. i planned to do this using the slopes of the 3 sides, then with y-y1=m(x-x1) using the other vertex and the point being checked see if the slope was the same sign and on the same side of the line. if this was true for all 3 then the point is inside the triangle the problem is i cant think of a logical expression for the if/then/else structure to show this anyone know what i should use or should i just go down a completely different route?

View 9 RepliesI'm working on a Pythagorean Theorem program that calculates the sides and angles of a right triangle. I have the side measurements and all that down, but I can't find the Visual Basic function that will allow me to calculate the angles from the side measurements. I've tried asin and sinh, but both give me the wrong measure.
View 2 RepliesI am working with a structure for a triangle.
Here is the code:
Public Structure Triangle
Shared a As Double = 1
Shared b As Double = 1
Shared c As Double = Triangle.FindC
Public angleABC As Double
[Code] .....
I am receiving an error in the function. "Triangle.angleABC" is generating :"Reference to a non-shared member requires an object reference". I need to find the hypotenuse for this Triangle. I have tried setting the variable as an object, this does nothing for the error. Also I've tried to use Public in the function and I receive an error stating it needs to be shared. I would like to work the the Structure with out running any functions on it first.

View 2 RepliesI need to create an application that creates Pascal's triangle the user would enter the number of rows, and using the formula (which i do not know... :/) would create the triangle. For example: the user enters 5 rows
triangle:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
as you can see the numbers are created by adding the 2 numbers above it starting with 1 at the top
