DirectX11 Quad in Screen Coordinates - C#/SlimDX -

-

How do I put a tractor on the plane near disappointment at a particular point defined by the screen space? I have frustrated corners and I have tried many things to give them names, but I could not save myself by getting a quarter at an accurate point, especially if I move the camera at all / rotate. I have had some limited success in keeping the center of quad at a certain point, but they are not able to offset them, so the corners are where I want to.

I have not tried about a perspective left hand launcher, the only thing I have tried, is going down the way of using a fixed artho camera with a fixed video camera and I think I I can go ahead in this way ...

A failed attempt is near me:

Vector 3 lower backconner = Vector 3 Transform coordinant (frust. Curators [1], see projection);

where frustum.Corners [1] is the bottom left corner of the bottom.

Using that vector would be a tractor center in the corner of the screen but I failed to offset it from the center, which I think is very easy because I just know that the special What is 'half' in depth Apart from this, if I move the camera then the tractor revolves around and I should have it steady. I am not sure whether it is FOV or what is throwing everything?

Technically I do not need screen coordinates, from where I can set the viewpoint corners and an object in it, I think it is an easy way to do that I I can not figure out yet.

Thank you.

One thing I have forgotten is that these quotes are instanced, hence the position vectors are added directly to the identity matrix in the peak shader. I do not think it should make any more complex, but it is probably worth mentioning.

I am using parameterized select questions in conjunction with my program and it works entirely, When I try to join the table Everything I have done is a small fraction: using (MySqlCommand cmd = new MySqlCommand (paramQuery) ToSql (), Connection)) /etc/ paramQuery.ToSql () Equal: "Select TableOne ID, Tableon, Department, Tablet. One by name table, Table 2 h Yes TableOnEID = @Pharmak "* / for (Int Index = 0; Index and Lt; ParamariX Parameter (.c calculation; Index ++) Cmd.Parameters.AddWithValue (paramQuery.Parameters (). ElementAt (index). , ParamQuery.Parameters (). ElementAt (index) .Value); / * ParamQuery.Parameters (). ElementAt (index) .k = "@most 0" paramQuery.Parameters (). ElementAt (index) .Value = "tableTwo.ID" * / MySqlDataReader Reader = cmd.ExecuteReader (); While (reader.Read ()) {// do stuff} } One of the tables I attempt to join is For the table, two with the same id for all. Is there something that I'm doing wrong?
