Question

我有一张课程表和考试表。我根据院士筛选列出它们。输入课程内容后，我会看到课程数据。我想在课程页面上查看属于该课程的考试信息，但由于存在不同的表格，因此无法显示。每节课的考试：期中考试和期末考试。例如 ;期中考试，A，期末考试； B期末考试，期末考试，补考。

models.py

matrix4f =  new Matrix4f().ortho(-2.0f, 2.0f, -1.5f, 1.5f, 1.0f, 1.0f);

FloatBuffer matrixBuffer = BufferUtils.createFloatBuffer(16);
matrix4f.get(matrixBuffer);

GL20.glUniformMatrix4fv(Shader.getLocation(shader, "transformationMatrix"), false, matrixBuffer);
