Vertex Buffer Object Manager

本文介绍了作者为满足新需求而设计的小型且灵活的Demo引擎。重点讨论了支持OpenGL (GL) 和Direct3D (D3D) 的必要性,并详细阐述了针对GL状态机特性,对顶点缓冲对象 (VBO) 进行封装的设计方案。文章还提供了类关系图和源代码示例。

It has been a long time that no update shows up here. Sorry....
I have been working on the requirement on a new Demo Engine, which is small and flexible.
After doing some survey all these days, I found that it is very necessary to support both GL and D3D to my engine.

For GL, it is state machine based so that an encapsulation for VBO is very vital for the rendering pipe line.

Here are the diagrams to show the class relationships:

Buffer diagram

Both vertex buffer and index buffer are inheritant from the buffer object class.
They provide  both reading and writing to the buffer object, bind/unbind, size calculation, etc.

VertexElement and VertexDeclaration are util class that helps to utilize the format of the rendering vertices. The user(programmer) can declare attribute of vertex, like position, normal, diffuse color, specular color, tangent, etc.

 



All the operation including creation, modification and deletion of buffer objects are calling from the BufferManager, which is a singelton class.

Here is the source code: VBO Manager

在金融行业中,对信用风险的判断是核心环节之一,其结果对机构的信贷政策和风险控制策略有直接影响。本文将围绕如何借助机器学习方法,尤其是Sklearn工具包,建立用于判断信用状况的预测系统。文中将涵盖逻辑回归、支持向量机等常见方法,并通过实际操作流程进行说明。 一、机器学习基本概念 机器学习属于人工智能的子领域,其基本理念是通过数据自动学习规律,而非依赖人工设定规则。在信贷分析中,该技术可用于挖掘历史数据中的潜在规律,进而对未来的信用表现进行预测。 二、Sklearn工具包概述 Sklearn(Scikit-learn)是Python语言中广泛使用的机器学习模块,提供多种数据处理和建模功能。它简化了数据清洗、特征提取、模型构建、验证与优化等流程,是数据科学项目中的常用工具。 三、逻辑回归模型 逻辑回归是一种常用于分类任务的线性模型,特别适用于二类问题。在信用评估中,该模型可用于判断借款人是否可能违约。其通过逻辑函数将输出映射为0到1之间的概率值,从而表示违约的可能性。 四、支持向量机模型 支持向量机是一种用于监督学习的算法,适用于数据维度高、样本量小的情况。在信用分析中,该方法能够通过寻找最佳分割面,区分违约与非违约客户。通过选用不同核函数,可应对复杂的非线性关系,提升预测精度。 五、数据预处理步骤 在建模前,需对原始数据进行清理与转换,包括处理缺失值、识别异常点、标准化数值、筛选有效特征等。对于信用评分,常见的输入变量包括收入水平、负债比例、信用历史记录、职业稳定性等。预处理有助于减少噪声干扰,增强模型的适应性。 六、模型构建与验证 借助Sklearn,可以将数据集划分为训练集和测试集,并通过交叉验证调整参数以提升模型性能。常用评估指标包括准确率、召回率、F1值以及AUC-ROC曲线。在处理不平衡数据时,更应关注模型的召回率与特异性。 七、集成学习方法 为提升模型预测能力,可采用集成策略,如结合多个模型的预测结果。这有助于降低单一模型的偏差与方差,增强整体预测的稳定性与准确性。 综上,基于机器学习的信用评估系统可通过Sklearn中的多种算法,结合合理的数据处理与模型优化,实现对借款人信用状况的精准判断。在实际应用中,需持续调整模型以适应市场变化,保障预测结果的长期有效性。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!
