问题 I have an Entity Person : @Entity public class Person implements Serializable { @Id @GeneratedValue(strategy = AUTO, generator = "PERSON_SEQ") private Integer idPerson; private String lastName; private String firstName; @Lob private byte[] picture; A repository public interface PersonRepository extends PagingAndSortingRepository<Person, Integer> {} A projection @Projection(name = "picture", types = { Person.class }) public interface ProjectionPicturePerson { byte[] getPicture(); } When i used

问题 Example. I have an XML document: <document> <region type="type1">text of region1 </region> some simple text <region type="type2">text of region2 </region> And I want it to be presented as text of region1 some simple text text of region2 The basic Eclipse coloring works independent from folding, as I know. But I need text to be colored depending on the xml info. Or maybe I need something other, than folding? It's probably easier to just manipulate StyledText, but I need other Eclipse Editor

问题 I have a Criteria using Hibernate like this public class Student { private Integer id,discriminatorColumn,discriminatorValue; //other stuff omitted for brevity } This entity has a discriminatorColumn which have values from 1 to 10 (never NULL ) and each discriminatorColumn has a discriminatorValue which have a value from 1 to 100 (never NULL ) Example: (Student data) ID DiscriminatorColumn DiscriminatorValue 1 1 3 2 2 4 3 1 13 And so. I am trying to get a SUM of the DiscriminatorValue

问题 So the problem is that I have a 3D projection of a rectangle that I want to turn into 2D. That is I have a photo of a sheet of paper laying on a table which I want to transform into a 2D view of that sheet. So what I need is to get an undistorted 2D image by reverting all the 3D/projection transformations and getting a plain view of the sheet from the top. I happened to find some directions on the subject but they don't suggest an immediate instruction on how this can be achieved. It would be

问题 I have mesh and 2 points on it - A and B . Each point lies on some triangle of mesh. The main goal is - draw correct line on mesh using 2 points. When points lies on triangles with different planes - I have problems with line drawing. What I do: CurrentTriangle = triangle on which the point A lies. While CurrentTriangle != triangle with point B: Get B projected( Bp ) to CurrentTriangle: moving B by -CurrentTriangle.normal * distance to plane. Find the exit point from the triangle - the

问题 I have something like this: var model = forumsDb.Categories .Select(c => new {c, c.Threads.Count}) .ToList() My Category object looks like this (pseudocode): public class Category { public int id {get;set;} public ICollection<Thread> Threads { get; set; } /***some properties***/ [NotMapped] public int ThreadCount {get;set;} } Now, in my model object, i have two items: model.c and model.Count . How can i map model.Count into model.c.ThreadCount ? 回答1: Define a strong type: public class

问题 I would like to draw circles in Cartopy in NorthPolarStereo projections, providing the center and radius in lat,lon units. Similar and excellent questions and answers are available for Basemap here, and for Cartopy in Ortographic projection here. However, I would like to use the NorthPolarStereo in Cartopy. Trying the latter approach, just changing the projection makes the circle fixed in the North Pole, ignoring the coordinates you give for its center. Any ideas on how to draw circles in

问题 I am trying to implement a texture cubic projection inside my WebGL shader, like in the picture below: What I tried so far: I am passing the bounding box of my object (the box in the middle of the picture) as follows: uniform vec3 u_bbmin; uniform vec3 u_bbmax; ... so the eight vertexes of my projection box are: vec3 v1 = vec3(u_bbmin.x, u_bbmin.y, u_bbmin.z); vec3 v2 = vec3(u_bbmax.x, u_bbmin.y, u_bbmin.z); vec3 v3 = vec3(u_bbmin.x, u_bbmax.y, u_bbmin.z); ...other combinations vec3 v8 = vec3
